Some users on Exchange 2007, FASmail or other email addresses on the UBC mail relay may be experiencing issues sending emails to some external domains (i.e. Hotmail, Gmail, Yahoo, Comcast, AOL, etc.) This is due to their servers blocking UBC mail relay from sending to them. The team has taken the affected mail-relay out of service as a temporary workaround until we can get unblocked. An update will be provided once the external domains remove the UBC mail relay from their blocklist.
