Hey.
Ive set it up through hotmail instead of the Rules on muss (couldnt seem to make it work properly just like you).
Go in hotmail, on the top right click options > more options > Send and recieve mail from other email accounts (2nd link).
This is how mine is setup:
Email:
[email protected]
POP3 Username:
[email protected] er.ca
Password: muss password
Incoming mail server: muss.cis.mcmaster.ca
Port: 995
Both boxes checked.
Delete the rules on muss, it might conflict with this.
Hope that helps.
