There will be some limitations on the yourspam.mcgill.ca interface Thursday June 11, while fixing a problem with the Puremessage antispam system.
During this time, all mail will be continue to be filtered and quarantined using the users' current white/black list settings. Users will still be able to log into yourspam.mcgill.ca, see any quarantined messages and release them if necessary, while noticing some slowness in performance.
However, users will not be able to modify their white / black list settings, or opt in/out of the service for today. Today's digest of quarantined messages will also be delayed.
