Unfortunately, we have discovered that some mail was returned to the sender during this incident for customers with short TTLs. Mail that was sent after a customer's TTL had expired may also have been returned to the sender, as well as mail from senders who had never sent to an AppRiver customer before, due to unresolved MX records. Some mail servers would have delivered a non-deliverable message back to the sender. In these cases mentioned, mail will need to be resent. We sincerely apologize for this inconvenience.

We experienced a brief incident (approximately 20 minutes) where our ARSMTP zone was not reporting back IP addresses. This issue is now resolved and no mail was lost, however, this may have caused delays for a few senders when sending mail to AppRiver customers who had extremely short TTLs, or for senders who had never sent to an AppRiver customer before. We will continue to monitor the zone and apologize for any inconvenience.
