SBS 2011 server rebooted after running OK for 6 months or so. Hundreds of previously unseen emails were delivered to users immediately after reboot.

Any ideas?

Hi

Can have more reasons, Queue was flooded. Roque Windows update which is fixed in the meantime, roque Antivirus / Spamrule/ Firewall setting is in place.

Best thing to do now is to check the Queue's regurlarly. It is possible the mails delivered were sent before the roque setting kicked in so it does not mean the problem is solved.

Queue checking is actually a regular routine, and the queues were empty prior to the reboot.

AV is Trend Micro WFBS vanilla install.

No changes made to Exchange AS settings either

Can you look at the logs to see what is recorded for the transport of one of the messages.

Also the headers of one of the messages would be helpful as it will let us know at what point it stopped and restarted.

On a side issue. I would highly recommend a regular server reboot (weekly and you can schedule it for after hours). This allows for all services to get a fresh start, locked RAM sectors to be freed, etc....

Cheers
Andrew

Turns out it was a 3rd party supplementary POP collector that was collecting off another server & had crashed months back and resumed operation when the server rebooted, resulting in the pick up of a bunch of mail that had gone to a backup MX during some outages.
