How to identify a forged email address - Article 3722

It is easy to fake what appears in the “from” or “reply-to” line of an email message. If you dig a little deeper, you can confirm the message’s true origin.

When you receive an email, the message header includes standard information, like “to,” “from,” and “subject.” But there’s also a more detailed full email header that can help you trace the message back to its original source, to see if that matches up with what the more basic message header says.

If the “from” in the message header doesn’t correspond with what you see in the full version of the email header, be suspicious of a scam.

If the email had actually come from Adobe, the “received” line would probably show that the email started its journey at

Also, if you scrutinize the “reply to” section of the full header, it indicates that your reply would be redirected to support-bx9v0dvbfjbebzau60jacqc68fsb9p@”—not the “newsletter@” address that the message appeared to come from.

Revealing the full header

The full header is not automatically visible, but it’s easy to reveal it through your email software.

Wath the speling …

Spelling and grammatical errors are good indicators that an email could potentially be bad.
