Eudora Problems & Solutions - Article 2787

NOTE:  ITS provides minimal support for Eudora because the application is no longer under development and does not officially support any operating system beyond Windows XP.

Following is a partial list of Eudora error messages, as well as a description of some problems and possible solutions. If you can't find a solution here, check ITS Eudora Frequently Asked Questions and Qualcomm's Eudora Technical Support.

Message text sometimes displays HTML codes instead of formatted text (Mac)

Symptom: The message text is displayed as:

<font size=3><b>Greetings from ITS!<br><br>
You can find additional Eudora information on our ITS E-mail web site.<br><br>

instead of:

Greetings from ITS!

You can find additional Eudora information on our ITS E-mail web site.

Solution: There is no solution at this time. The "Content-Type:" message header is missing, so Mac Eudora is unable to correctly display the HTML-formatted text.

Sometimes when I send a message to a group of people, a "Too many recipients" error message is returned

Symptom: The error message usually contains a list of several e-mail addresses similar to the following: "<>... Deferred 452 4.5.3 Too many recipients

Solution: The "too many recipients" errors are temporary errors and delivery will get retried after a few minutes. When you see this, though, it means that there is at least one hard delivery error at the beginning of the delivery transcript. Look for "The following addresses had permanent fatal errors" and check the addresses listed for typographical errors, user unknown, etc.

I installed Norton AntiVirus and now Eudora's response time is very slow

Symptom: After installing Norton, Eudora is now slow to launch, using the various features is slower, typing messages is slow, etc. Note: These symptoms appear to impact some users with the following configuration: Windows XP, Norton AntiVirus, and Eudora mailboxes stored on the network drive.

Solution: Double-click on the Norton AntiVirus icon on the Taskbar, select Configure | File System Realtime Protection, and under "Drive types:" uncheck Network. Click OK.

Unable to dock Mailboxes window

Symptom: The Mailboxes window doesn't redock properly.

Solution: Right-click in the Mailboxes window and select "Allow Docking" from the menu. Grab the Mailboxes window by the Title bar and move it to the upper left-hand corner of the main Eudora window, directly under the Trash icon on the Toolbar.

A message must have a recipient (To: or Bcc: field) before it can be queued or Recipient Missing (Windows)
Sorry, can't queue this message; all messages must have addresses in the to: or bcc: fields. 0,{compact:149} (Mac)

Symptoms: You are unable to Queue or Send a particular message because of "recipient missing" or after you type an address or nickname into the To: field, Eudora appears to erase the entry.

Solution: Check to see if you have entered a nickname into the address book with no address associated with it, i.e., the address(es) tab in the Address Book is blank. After you enter the nickname, Eudora replaces the nickname with the blank address and it looks like Eudora is erasing the entry. Find and delete that nickname from the address book or correct the nickname entry by entering an address under the address(es) field.

Could not open the file x for reading
Cause: Access permission denied. File may be marked as read only or locked (13).

Symptom: You are unable to Send e-mail. Eudora displays the above error message.

Solution: An e-mail message in the Out mailbox has an invalid attachment. Select Window. The "bad" message should appear in the Window pull down menu. Open the message, review the "Attached:" field header and correct the "bad" attachment line. You may also need to review the Out mailbox. Check the "Attached:" field of any e-mail messages that are still queued. 

Send Queued Messages is greyed out

Symptom: You create and queue a message, but when you try to send the message, Send Queued Messages is not highlighted, i.e., is not selectable. The messages appear as queued messages in the Eudora Out mailbox, but are never sent.

Solution: Check the computer date. Update the Date/Time in the Control Panel to the correct date.

I said: PASS <shhhh! Don't tell anyone.>

Symptom: When you select Check Mail, Eudora returns the error message
There has been an error transferring your mail. I said:
PASS <shhhh! Don't tell anyone.>
and then the POP server ( said:
ERR Unable to process From lines (envelopes), ...

Solution: Call the ITS Help Desk (384-HELP) and alert them of this exact error message. This can be caused because Leave Mail on Server is checked in your Eudora Options (Settings) or you have received one or more very large attachments.

You get an "Inbox corrupted, would you like to rebuild it?" message.

Symptom: Eudora opens and immediately displays the message "Inbox corrupted; would you like to rebuild it?" You answer yes and get the message "Eudora performed an illegal operation", and Eudora shuts down.

Solution: Some part of the In mailbox (in.mbx) is corrupted and needs to be deleted.

  1. Use Windows Explorer or My Computer to delete the in.toc file (the Table of Contents file associated with the In mailbox) from your Eudora directory. Restart Eudora.
  2. If the problem persists, some part of the in.mbx is corrupted. Make a copy of in.mbx (e.g., inold.mbx) and save it outside the Eudora directory. Rename in.mbx to inbox.mbx. Use Notepad or WordPad to edit the inbox.mbx file. Delete the last message, and then save the file into a new mailbox named in1.mbx. Do not save the changes to inbox.mbx. Restart Eudora.

    Note: The mailbox files, somename.mbx, are ASCII text files. Each message in an .mbx file is separated by a line that starts with "From ???@???"; e.g.,
    From ???@??? Wed Jul 02 17:54:11 1997

  3. If you can open the new mailbox, then the problem was the last message, which is no longer a part of the in1.mbx file. However, if you cannot open in1.mbx, exit Eudora and open in1.mbx with Notepad or WordPad again. Copy some of the last messages to another new mailbox, in2.mbx for example, delete those same messages from in1.mbx, and restart Eudora.
  4. If the problem persists, continue this procedure until you find the corrupted message. Delete that message. (If you need to keep the corrupted message, print it from Notepad before deleting it.)
  5. After the corrupted message has been deleted, restart Eudora. Transfer the messages from mailboxes you created (in1.mbx, etc.) back into your In mailbox and delete those other mailboxes. Also delete the backup copies of your In mailbox, called inbox.mbx and inold.mbx in step 2 above.

MAPI - File | Send... not available or isn't working properly

Symptom: You have set Eudora Tools | Options | MAPI to "When Eudora is running" or "Always", restarted Eudora and Microsoft Word, but within Word, the File | Send pull-down menu selection still does not appear.

Solution: Edit the "win.ini" file, locate the [Mail] section and add the line "MAPIX=1".

[Mail] MAPI=1 MAPIX=1

Note: "MAPI=1" should already be there.

If you have problems with File | Send (e.g., nothing happens when you choose this option) check your settings in Start | Settings | Control Panel | Internet Options. Click on the Programs tab and verify that the E-Mail setting is Eudora.

Note: For additional information about MAPI, see Qualcomm's Eudora MAPI FAQ.

Multiple copies of the same message(s) are displayed in the In mailbox

Do you receive the same one identical e-mail message many times, possibly as many as 200 copies of that same message, each time that you Check Mail?
This is probably an e-mail looping problem. If the e-mail message originated from a listserver, try to contact the list owner. Many times the situation will clear itself up because someone else who is subscribed to the list will already have contacted the list owner. You may need to temporarily unsubscribe from the list.

Do you receive many repeated e-mails over and over again, so that each time you Check Mail, you receive that same group of varied e-mail messages?
You may have "old" attachments waiting to be delivered. Eudora periodically attempts to redeliver these messages. In Eudora, choose Tools | Options and select the Incoming Mail category. If Server configuration is POP, uncheck the option Skip messages over nn K in size. This will download all attachments. If this is not the problem, call the ITS Help desk (384-HELP) and alert them of the exact error message. This can be caused because you have Leave Mail on Server checked in your Eudora Options (Settings) or have received one or more very large attachments.

Options settings are not saved

Symptom: You make a change under Tools | Options and click on the OK button, but the change is not saved.

Solution: The eudora.ini file may be corrupted. Select Tools | Options and note all important information, including at least information listed under Getting Started. Exit Eudora. Use Windows Explorer or My Computer to rename the eudora.ini file to eudora.bad.
Save a new eudora.ini file 3.x | 4.x | 5.x | 6.x to your Eudora directory. Launch Eudora and select Tools | Options. Fill in the information previously recorded.

Several messages are concatenated. From ???@??? appears. Subject and sender do not match.

Symptom: You open a message and it contains several concatenated messages. Sometimes the subject listed in the mailbox summary does not match the subject in the message. Sometimes the line "From ???@???" appears between the concatenated messages. Also "From ???@???" might be appended to the text of another line.

Solution: The fix for the immediate problem is:

  1. Exit Eudora.
  2. Copy the mailbox.mbx and mailbox.toc files of the damaged mailbox to a backup directory.
  3. Use Notepad or WordPad to edit the original mailbox.mbx file.
  4. Edit | Find | ???@??? (Wordpad) or Search | Find | ???@??? (Notepad).
  5. Edit the file as necessary so that all of the "From ???@???" lines start in column one.
  6. Save | Exit - be certain to save as text. (See Note 1 below for exception.)
  7. Launch Eudora.
  8. Eudora will display the message "mailbox.TOC has been damaged."
  9. Click on Create New to allow Eudora to rebuild the TOC (Table of Contents).

Note 1: If all of the "From ???@???" already start in column one and you did not actually need to edit the mailbox, delete the mailbox.toc. This forces Eudora to rebuild the TOC file.

Note 2: It appears that Eudora sometimes has an incompatability with Novell Servers 3.12, which may cause the above problem. To determine if this is the case, simply delete or transfer any messages out of the problem mailbox and then compact the mailbox (click on the mailbox size display in the lower left corner of the mailbox). If Eudora displays the error "File may be locked (13)" or "Could not open the file h:\eudora\mailbox.toc for writing. Cause: Access permission denied. File may be locked (13)", then the above garbled messages problem will reoccur each time the mailbox is compacted.

Solution for Note 2: Please report this problem to the (384-HELP) to help us track and determine the underlying cause.

  1. Fix the mailbox once again as covered in the steps outlined above.
  2. Move or copy all of the Eudora user files from h:\eudora to c:\eudora
  3. Change h:\eudora to c:\eudora in all Eudora shortcuts.
  4. Refer to Backing Up Eudora Mailboxes and Files.

Terminate Remote instance. An instance of Eudora may be running on a remote computer.

Symptom: When you first start Eudora, a Remote Instance Window is displayed which states "An instance of Eudora may be running on a remote computer. Accessing a mailbox from two instances of Eudora may lead to data corruption. Please indicate how you wish to proceed."

Solution: This usually happens after either Eudora or your network crashes. Select Terminate Remote Instance. If this is a recurring problem, check to see if you have an owner.lok file in your Eudora directory. The owner.lok file prevents Eudora from accessing the mailboxes, so delete this file.

Symptom: After selecting Terminate Remote Instance as suggested above, Eudora crashes and then causes Windows Explorer to crash, forcing a reboot of the computer. This happens until the owner.lok is removed. No problems occur until a Eudora session hangs, leaving the owner.lok file.

Solution: Click on the Close Button (the X in the upper-right corner of the Eudora window) or close the remote instance on the task bar to recover without crashing your system, rather than clicking on any of the three buttons displayed. Delete the owner.lok file from your Eudora directory. Add the line CheckOwnerFreq=0 (ver. 3.x) or OwnerLok=0 (ver. 4.x and up) to the [Settings] section of your Eudora.ini file (in your Eudora directory) to prevent Eudora from checking for an owner.lok file on launch. Note: If you add this setting, you need to make sure that you don't inadvertantly launch Eudora multiple times.

The recipient "Smith_John" is not acceptable to your SMTP server. The message is not sendable until the recipient has been changed.

Symptom: You are unable to Send e-mail. Eudora displays the above error message.

Solution: An e-mail message has been addressed incorrectly. Select Window. The "problem" message should appear in the Window pull down menu. Open this message. Review the e-mail addresses in the To:, Cc:, and Bcc: fields. Remove the entry for Smith_John in any of these fields. You may also need to review the Out mailbox. Check any e-mail messages that have a status of "Queued".

This program has preformed an illegal operation and will be shut down.
If the problem persists, contact the program vendor.

Symptom: Eudora displays the error message shown above. When you select the Details button, "Eudora caused an invalid page fault in module KERNEL32.DLL..." is displayed.

Solution: Exit Eudora. Make a backup copy of the eudora.ini file. Using Windows Explorer or My Computer, edit the eudora.ini file in your Eudora mailbox directory. Delete all of the sections except [Settings], [Mappings], [Personalities], [Persona-xxx], [Dialup], [Debug], and [Directory Services]. Save this file and restart Eudora.

When I select Message | New Message To, there are names (recipients) on the list that are not in any of my address books.

Solution: Open the H:\Eudora\RCPdbase.txt file (if your mail is stored on the server) or C:\Program Files\Qualcomm|Eudora\RCPdbase.txt file (if your mail is stored on your hard drive), remove the nickname from the file and resave the file.

Eudora recipient cannot view attachments that an Outlook user is sending

Symptom: An Outlook user is sending a Eudora user a Microsoft Word document but the recipient cannot view the attachment — it is an RTF file.

Solution: Have the sender change their Outlook default message format for all new messages. On the Tools menu, click Options, and then click the Mail Format tab. In the Compose in this message format list, click the Plain text format.

Recipients complain that you are sending blank messages

Symptom: You send a message to several people, but when certain recipients (Eudora IMAP users) view the message, there is no text in the body of the message — they only see the To:, From:, and Subject: fields.

Solution: If you have a signature file, you may have corrupt characters (which you can't see) in the file. Delete the signature file, create a new one, and then send a test message to one of the recipients who was receiving a blank message.

When printing a message, header information is incomplete. (Windows)

Symptom: When printing a message from the preview pane or mailbox summary, the header information is incomplete, e.g., date, time, sender, subject info is missing.

Solution: Double-click on the message to open it. When you print the message, all header information will be included.

"Choose Mailbox" window is partially viewable. (Mac)

Symptom: When you select the "Choose Mailbox" window to select a mailbox for deleted IMAP messages (Special | Settings | Personalities Extras), the last line is partially viewable.

Solution: Change your 'Large System Font' to something other than Chicago.

Changing SSL settings may cause connection problems

Symptom: If you change your SSL (Secure Sockets Layer) setting to one of the "Required" options, you may suddenly experience problems sending or receiving mail.

Solution: Change your SSL setting back to "If Available, STARTTLS" or "Never" in Eudora for Windows and "Optional (TLS)" or "None" in Mac Eudora. Our mail server supports SSL for incoming mail.

Domain Name System error (Mac)

Symptom: Mac users who choose to have Eudora start their ISP connection, (e.g, rather than first connecting to an ISP and then starting Eudora), may receive a 'Domain Name System' error.

Solution: This is a known problem where ARA (Apple Remote Access) reports to Eudora that a connection is established. Eudora acts on this information immediately, attempting to send/check mail. Since the connection is not really established, the attempts to check and send maill fail.

Launch Eudora. Create a new message and copy the link below into the message and then double-click on the link. Note: This will force Eudora to pause two seconds before attempting to send/check mail after ARA reports that a connection is established. If the problem persists, click on the link again and up the setting.


'Error reading from network. Cause: Connection closed by foreign host'

Symptom: Win Eudora 5.1 users experience a dropped connection when attempting to check mail.

Solution: This problem is specific to Eudora 5.1 users running on a Windows 95 OS. Select the Checking Mail category and change the "Secure Sockets when Receiving" option to Never. Windows 95 users will not be able to take advantage of SSL.

'Error reading from network - tired of waiting for server 10100'

Symptom: Win Eudora 5.1 users may experience problems of slow downloading of e-mail messages or receive the following error: 'error reading from network - tired of waiting for server 10100'.

Solution: In Eudora: 1) choose Tools | Options, 2) select the Advanced Network category. Set the Network Buffer Size to 8192,
3) select the Checking Mail category. Change the "Secure Sockets when Receiving" option to If Available, STARTTLS, 4) Click the OK button to save your changes.

SSL Negotiation Failed: Certificate Error: Cert Chain not trusted...'

Symptom: Win Eudora 5.1 users may receive the following error: 'SSL Negotiation Failed: Certificate Error: Cert Chain not trusted. Try adding this certificate to your certificate database for SSL to succeed Unknown certificate chain validation error: Code (3015) Cause (-6995)'.

Solution: In Eudora: 1) choose Tools | Personalities, 2) Right-click on <Dominant>, 3) choose Properties, 4) select Incoming Mail, 5) under Authentication style: 'Secure sockets when Receiving' choose If Available, STARTTLS, 6) choose 'Last SSL Info', 7) click on 'Certificate Information Manager', 8) select US, Iowa, Iowa City, The University of Iowa... , 9) select Add to Trusted button, 10. select the Done button, 11) select the OK button to save your changes. (NOTE: You will need to do this for each Personality).

Eudora 5.1.1 Mac OS X installer is SLOW

Symptom: When trying to install Eudora 5.1.1 for Mac OS X, the installer seems to take forever.

Solution: This is a known issue with the installer for Mac 5.1.1 for Mac OS X — if you have formatted your drive with UFS. The installer takes several minutes to find your current Eudora installation and registration information. The issue will be addressed in a future installer.

When checking mail I get the following message: "SSL error... An error occurred with a temporary file while transferring your mail"

Symptom: When you do a check mail you get the following message: "SSL error... An error occurred with a temporary file while transferring your mail".

Solution: We have seen this problem with Eudora POP users who keep their mailboxes either on their hard drive or a network drive. The SSL error seems to be caused when you do a Check Mail and a message w/an attachment containing a "particular" virus is trying to be downloaded. As Eudora is processing the message with attachment, the server or desktop anti-virus software (e.g., Norton) detects a virus and tries to rename/quarantine it. Eudora steps back in to finish processing the attachment, but can't find the attachment because it has been renamed/quarantined.

Current work arounds: 1) Users who keep their mail on a network drive will need to log into WebMail and delete the message with the attachment. The next time they do a 'Check Mail' in Eudora, the mail will be downloaded. OR 2) Users who keep their mail on their hard drive and are running anti-virus software on their desktop (e.g., Norton) should set their virus scanning to NOT include the Eudora Spool folder.

When I launch Mac Eudora 5.2.1, I get an "Error Type 3" message

Symptom: When you launch Mac Eudora 5.2.1 you get an "Error Type 3" message.

Solution: Download the CarbonLib 1.6 from Apple's website, then restart the computer and launch Eudora.

If the above link doesn't find the CarbonLib file, go to Apple's website, click on Support and in the "Search Support" field type in CarbonLib 1.6.

'Could not get mailbox list' error (Mac)

Symptom: When checking mail, you get an error message: Could not get mailbox list. Unable to get the required mailbox list from the server.

Solution: Keychain Access (Control Panels) must be loaded and have a keychain configured. See SSL Setup (Mac) for details.

When checking mail I get the following "Server does not support SSL" error message

Symptom: When checking mail, you get the following: "Server does not support SSL" error message.

Solution: In Eudora version 5.1 or later, you will need to configure SSL for checking mail:

  1. Select Tools | Options and click on the Checking Mail category.
  2. Select Required, Alternate Port from the "Secure Sockets when Receiving" pull-down menu.
  3. Click OK.
  4. Exit Eudora and restart.
