Mail Routing

RSUG Mail Routing provides incoming and outgoing mail routing services for University of Michigan email users.

Incoming Mail
Incoming mail to the umich.edu domain is routed through servers which utilize the University of Michigan Online Directory to determine the proper destination for mail sent to "@umich.edu" addresses.

If a message is sent to "uniqname@umich.edu" it then goes to the address(es) listed in the "E-Mail Forwarding Address" field of the person's online directory entry. For instructions on how to edit University Online Directory entries, see the Online Campus Directory Help page.

Mail routing for directory groups is also provided. See the Working With E-Mail Groups Using the U-M Online Directory On the Web page for details.

Outgoing Mail

Mail Routing provides an authenticated server for outgoing mail that delivers mail locally and off campus.
smtp.mail.umich.edu accepts SMTP, or Simple Mail Transfer Protool, connections from users' mail clients, and then routes the users' sent emails to their requested destinations.

Usage of the smtp.mail.umich.edu is restricted to University of Michigan students, staff, and faculty members.
To use the outgoing mail server, consult your IMAP or POP mail client's documentation. Enter the full address of the server, smtp.mail.umich.edu, in the pertinent configuration field. This field is typically labeled "outgoing SMTP server".


Outgoing Mail

Mail Routing provides a mail relay service that will relay mail on behalf of campus machines, devices, and applications that are unable to use authenticated SMTP for sending mail.

The mail relay service is intended to relay legitimate U-M mail, such as mail from U-M networking devices that send automated mail but that do not support authenticated SMTP. Some examples are routers, printers or scanners that generate notification messages to administrators.

Departments must register their U-M campus IP address(es) with the service in order to use it. See the Guidelines and Registration Form for Use of the ITCS Mail Relay Service page for details.
