Get to your (Gmail) ...@u.northwestern.edu account, select:
Settings > Accounts and Import > Send mail as
Click in "Add another email address." Write your math email address ...@math.northwestern.edu in the space reserved for that purpose and click "Next Step." In the next screen use the following parameters:
SMTP Server: imap.northwestern.edu Port: 587 (if does not work try 465) Username: (Your NU NetID) Password: (Your NU password) Secured connection using:  SSL
Click "Add Account", and you will receive a confirmation email.
After that you should be able to select ...@math.northwestern.edu as your outgoing email address.
