IMAP Service stops randomly

[jdanieli]

I'm using enterprise 4.22 and the IMAP service stops randomly. Sometimes it stays on for weeks and other times it shuts downs after a few hours. We are also using SSL with the service 100% of the time. Is there a fix for this or some way to automatically monitor it and restart it when it stops? All the other services remain running with no problem.

We are also seeing this type of issue. We are running version 5.11. Any ideas?

Dear all, We meet the same issue with Mailenable Enterprise 5.10.
IMAP service stops unexpectingly withour any relevant information in the logs file.
MXscan installed.
A fix would be deeply appreciated...

Hi,

Please upgrade to version 5.5 located here http://www.mailenable.com/download.asp as there has been significant changes to the IMAP service and message indexing.

[arnaud]

Ian,
Yes we received the 5.5 annoucement just a few minutes after posting! We updated immediately, so far so good.
Thanks
Arnaud

For whatever reason, since version 4. something I noticed that anomoly appear. What I do is go to the services program in Windows Server and change the option for restart upon failure for all three times on the Recovery tab. That keeps my IMAP online. Each time to upgrade to the next version (minor or major), double check to make sure this hasn't changed.
