Managing Unwanted Email

Unblocking Your Email Server

When sending mail to a university email address, you may find that delivery fails and that the message is returned to you. This may be due to the university’s inbound spam defenses. Your returned message may include one of the following error messages:

See the relevant article above for details on why your message was rejected.

If you are sending mail from a university address and your message is flagged as spam by the university's spam filters, you will receive an automated response with the tag [UTEXAS: SPAM DETECTED] prepended to the subject and a short explanation. Please see Sent Email Returned With [UTEXAS:SPAM DETECTED] in Subject Line for more information.

ITS employs many techniques to combat unwanted email, including blacklisting known spammers and requiring authentication and encryption on all outgoing email messages.

Due to the dynamic and evolving nature of spam, the university's spam filters are constantly adapting and changing. The above list represents the most common reasons that inbound messages are blocked as spam; however, other factors are considered and may be taken into account as trends change. The university may expand this filtering if needed.
