Hello, I ‘ve an issue concerning smtp mail transport. After a planed downtime of our MS Exchange server, our SOPHOS UTM HA no longer sends emails, either in or out. The Sophos system stayed online intentionally during the downtime of the Exchange to "buffer" emails. I think there were too many emails and Sophos that can’t buffer all because they couldn’t forwarded to the Exchange. The "Mail Manager" seems to hang up, in the "SMTP-LOG" tab of the "Mail Manager" comes after a few minutes, the error message "request faild five times in a row".
UTM 9
HA 2 x SG 310
Firmware version: 9.605-1
Pattern version: 166285
(Second HA Node switched off at the moment)
