E-Mail Settings for Authenticated SMTP

S4341 • December 2012

This document provides instructions for configuring email clients to use ITS's authenticated SMTP server (smtp.mail.umich.edu). This vehicle for sending outbound mail is an alternative to using your regular mail account for sending mail for those whose university business needs are not met by their regular account.

Troubleshooting

If you are unable to send mail after changing your settings, here are some things to try:

  1. Check your settings:

    • the SMTP/outgoing mail server should be smtp.mail.umich.edu.

    • Authentication is required.

    • SSL must be used. (Note that TLS is a form of SSL. In some programs, we recommend that you select TLS.)

    • The port number for SMTP should be either 465 (used by most Microsoft mail programs) or 587 (used by most non-Microsoft mail programs).

  2. Try switching the port number. Sometimes this helps. If you entered 465, try 587 instead. If you entered 587, try 465.

  3. If you are running personal firewall software or anti-virus software other than the versions of VirusScan for Windows or Sophos Anti-Virus for Macintosh that ITS distributes, it is possible that your security software is blocking port 465 or 587. Try disabling that software, then test. If that is indeed the cause, set your security software so that it does not block those ports.

  4. If you are using an ISP other than U-M (for example, Comcast, APL, SBC, etc.), your ISP may be blocking access to ITS's SMTP server. In that case, you must use your ISP's recommended SMTP server settings. Check your ISP's website or contact your ISP for instructions and assistance.
