[courier-users] Really over a barrel here...

[Jonah Sullivan]

We are running a mail server using Postfix, Maildrop, and Courier-IMAP with SSL for incoming and outgoing post.  We are having problems with every client, but perhaps the most bizarre is with M$ Outlook:   I currently have 4 IMAP boxes located on this server in my Outlook list.  _Every_ time I go to check mail at these accounts, I will be disconnected from at least one of the sessions with a message telling me that there may be ‘server or network problems or your timeout interval is too short’.  Also, about 90% of the time I will get an error (0x800CCC0E) fetching new headers from a successful connection which subsequently stays open.   The error log reports nothing.  In fact, it shows successful connections for each account and claims that there are no headers in the account that errors-out.  However, if I check the box individually, I find I do have messages.   The server timeout is set to something ridiculous like 2 hours.  The IP concurrency limit is 10.  The server has no other problems sending or receiving and is actually very well-behaved otherwise.   Note:  This server is also running Mailman, named, apache, and the CA.  We are running the latest versions of everything mail-related including Squirrelmail (on a different server) which works flawlessly.   I’ve invested tens of hours pouring over mail list and newsgroup archives.  I’ve tinkered with everything I can think of to tinker with.  I’m at my wits end here… HELP!! =P   -j
