On November 17th, 2011 between 10:15 and 10:40, users may have received a bounce-back notification message when attempting to send a message to an @ubc.ca email address. Please note that this was due to an unforeseen issue with this scheduled change: https://bulletins.it.ubc.ca/2011/11/17/routing-change-of-e-mail-sent-to-the-ubc-ca-domain-november-17-2011-1000-1100/
Because of this unanticipated problem, the change has been reverted and this routing change will be deferred to next week. All issues with mailing routing to the @ubc.ca domain has now resolved. Affected messages during this time frame will need to be resent.
