Many ISP's are restricting access to their SMTP servers to users within
their domain; this helps thwart spammers who often find an suspecting ISP
with an open SMTP server to relay their spam.

There are a couple ways around this.  First, you can see if your ubc.ca
service provider has anSMTP server you can use.  Or, you can run your own
SMTP server on your machine.
