How do I configure my client to use authenticated SMTP?

Changing Your SMTP Server Port


To help reduce the increasing number of spam mail messages coming into our email system and to ensure SMTP authentication, we have changed the address used to configure email programs to send mail through UNC SOM's SMTP servers. If you want to configure your email program to use to relay mail, you must change the SMTP port setting to 587.

This applies to any user, on or off the medical school campus, who wants to use as their outgoing SMTP host.

Below are instructions on how to change the SMTP server and port settings on email clients supported by OIS. These instructions assume that you have previously configured the email clients below to work with UNC SOM's e-mail system. If you have not already configured your email client, instructions are available here.
