We're using Symantec Mail Security for SMTP. Every so often (perhaps every few weeks) we start getting an email alert like the following:
Symantec Mail Security Alert Notification for xxxx
ALERT NOTIFICATION
The following system components are not responding/working:
Host Component Problem
Local Host MTA (Inbound) Stopped
MTA (Outbound) Stopped
MTA (Delivery) Stopped
We continue to get the same alert every hour, on the hour. Mail delivery does not seem to be affected. Restarting the server fixes the issue and messages stop, at least for a few weeks anyways. There has to be a better solution to this than the restart "solution". Better yet, why is this happening?
