Well this probably isn't the right way... but here's what I did. Seems to work:
Settings -> Mail, Contacts, Calendar
Name: name
Address: email address
Description: email address
Host Name: muss.cis.mcmaster.ca
Username:
[email protected] ster.ca (although in retrospect could probably just put lawleyc)
Password: self explanatory
SMTP: muss.cis.mcmaster.ca
Rofl. Like I said. Probably wrong, but I can send and receive emails just fine. xD
