My IMAP problem remains however. Thunderbird simply cannot access the
contents of certain folders. This is no longer consistently Sent, Trash
and Drafts. I nuked all my Thunderbird account settings and rebuilt
just the one to the new Courier server. Now I have my Sent items back,
but some of my shared folders have developed the problem. Also, I think
is is somewhat intermittant. Some folders won't read and then at other
times I can get them. Others consistently work (e.g., Inbox) or
consistently don't. Outlook has none of these problems -- my other
users seem to not have these problems with Thunderbird. It would be a
great shame if I'm stuck with Outlook because of this. Anybody have an
idea what might cause this or where I might even start looking?
You probably have thunderbird's max imap connections set to 5 while
Courier by default only allows 4 imap connections per IP address. I'll
bet it gives you the error on the 4th folder you click on...
Either change the number of IMAP connections TB attempts to make (Tools,
Account Settings, Server Settings, Advanced, Maximum Number of Server
Setting to Cache) or bump the number of IMAP connection Courier-IMAP
allows from an IP (MAXPERIP= setting in /etc/courier/imapd). I suggest
setting TB to make no more than 2 connections per client if you have
lots of users otherwise it will create a lot more load on your server.
Defaulting to allowing 5 connections is really a braindead idea for TB.
If your curious as to why MAXPERIP defaults to 4 for Courier, read
through the courier-imap list archives for the past month, there's a
large thread in there.
