The final phase of the SpamTitan cutover was completed on Tuesday, May 21st. Following a staged transition that took place over several days prior to “warm up” the sending addresses, the outbound mail routing of the remaining domains was changed to the SpamTitan systems. Systems were monitored closely during all phases of this changeover. As our network addresses did not yet have a pre-established reputation as a safe sender, some unexpected situations were encountered that led to some minor delays and some bounces of outbound mail for a few users. Mail flow was never halted entirely, nor was complete blockage encountered on any receiving domain. However, any potential disruption is unacceptable to our team. We have worked vigorously with the affected email hosting providers to ensure any deferments were resolved as quickly as possible.

At this time, all reported blocks of our outbound IP addresses have been cleared. We are continuing to closely monitor our systems to ensure that additional issues do not arise. We cannot apologize enough for any inconvenience that was caused by the transition process. If you have any further concerns or experience any issues please notify our support team immediately.
