In an effort to prevent phishing and help UI students, faculty, and staff identify potentially fraudulent email, external email tagging will be enabled on Tuesday, March 5, 2019. All email received from outside of the University of Iowa (these can be both suspicious and harmless) will be tagged with [External] in the subject line. UIHC's implementation of external tags as well as our internal pilot has been successful. Find additional information and answers to frequently asked questions in the External Email Tag support article.
