Email Settings for Authenticated SMTP

Overview

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

General Configuration Information

Use smtp.mail.umich.edu for the outgoing (SMTP) mail server and use SSL for authentication.

Apple's Mail Application

  1. From the Mail menu, select Preferences.

  2. Click the Accounts button.

  3. In the list of accounts on the left side of the window, select the account you want to modify, and the configuration information will appear to the right. If you prefer, you can click the + sign to create a new account.

  4. Under the Account Information tab, click the Server Settings button at the bottom of the window. Do not change your current Account Type setting. An old ITCS IMAP account is shown here; you may be using a different 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 Mac that ITS distributes, it is possible that your security software is blocking port 465 or 587. Try disabling that software, then testing again. If this 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.
