I used this Ubuntu tutorial to get set up. I'm using Courier-IMAP and POP3 for reading mail which seems to be working without issue. However, the credentials used to read a mailbox are not working for SMTP. I can see from /var/log/auth.log that PAM is being used, does this require a UNIX user account to work?

Mostly on a system the smtp/imap check is just a lookup of you system account. And there are no system accounts like whatever@domain.com. So pam cannot find such a user and so rejecting authentication. Take a look in /etc/pam.d/smtp If you really want using pam, which I would suggest you, you can use a mysql table for your authentication or other fancy things. Take a look at pam-mysql e.g. Either use a apropriate setup
