Topic: IMAP timeouts

[mapangojoe]

Hello all.  I have a SME server (PIII-1GHz, 768MB RAM, RAID5, SME 6.01) with aproximately 50 users on it.  I just moved the users from getting mail from a hosting company, to using the IMAP server in the SME server.  I am having the users regularly complain about timeouts using Outlook (various versions) and Evolution.  

I have looked in the logs for something obvious.  I have repeatedly checked top, and the server seems to just idle.  I have never seen top go over 6%, and it often is far below that.  

Does anyone else see this issue, or has anyone else had a similar setup?  I'm just looking for ideas on what to try next.

Hi Chris
You could try increasing the Outlook IMAP server timeout setting as per this howto http://itinfo.mit.edu/answer.php?id=7014. But whether that fixes the problem or not is anyones guess

It could also be a concurrency problem.  I ran into a problem like this after using IMAPCOPY.EXE to import email to a SME7.0Beta5 server.  One of my users has an enormous mailbox with over 100 subfolders.

When testing for this user I found that I could onle check through 6 directorys before I was locked out by the concurrency rules.

On 6.x it's a little different.  

/sbin/e-smith/config setprop imap ConcurrencyLimit 200
/etc/e-smith/events/actions/imap-conf

In 7.x you have to control this in /var/service/imap/run

I don't think this is really a bug... I mean what user in his right mind is going to migrate email the way I did.  I did it just for testing.
