If anyone has trouble having their alias FASmail account forwarded to @stat.ubc.ca, here's user experience reported:
1. Ask UBC IT to created an alias Firstname.Lastname@ubc.ca (I didn't want my CWL@mail.ubc.ca address distributed widely, since that's my CWL id, and I don't like it being out on the interwebs too much). Make sure you have added the email address you want to forward to into your contact list: after logging in at https://www.mail.ubc.ca using your CWL account, access People menu from the top left Menu icon, then add a new entry for "Your contacts"
2. Created an Inbox rule (go to the little gear wheel on the top right of the web interface www.mail.ubc.ca) to have my FASemail forwarded to @stat.ubc.ca *BUT* there is a trick! Here's what took IT central 2 weeks of emails back and forth to figure out:
3. Split the rule into two: one to forward emails only, and another one to delete the forwarded emails, and make sure the "delete" rule is set up after the forward one.
4. If you don't do 3 above, you will have your "alias" email forwarded, but email to your CWL@mail.ubc.ca will disappear in thin air
5. With 3, all my FASemail (those sent to CWL@mail.ubc.ca and also those sent to Firstname.Lastname@ubc.ca) get forwarded to @stat.ubc.ca
