I have an odd problem with one user account. When trying to login to
Squirrelmail, the login will hang for several seconds then result in:
ERROR: Connection dropped by IMAP server.
Query: LOGOUT
This is now happening with more than one user account. The problem has
returned on the one that I *thought* I had fixed plus it's showing up
on multiple other accounts. Yet some still work.

Anybody have any suggestions? I'm just about ready to give in and do a
fresh install of CentOS and Qmail, then import all of my old messages.
Except that I'm not entirely certain that the problem won't follow the
old messages to a new box.

Also, how many SM users are there, and how many IMAP that are not SM?
All users (about 94 total) have access to Squirrelmail. Of those 94,
most only sign in maybe once a week, if that, and 27 accounts would
only rarely sign in to Squirrelmail - usually when out of office.
Non-SM IMAP - the 27 accounts that I already mentioned - will
eventually all be on non-SM IMAP but five or six are currently still
on POP3.
I don't notice a problem here off hand. I am curious to know how you
came up with the imap_capability parameters, given that they're not in
the stock config. Same goes for the mailbox sections. BL, should these
be included in the stock QMT configuration perhaps?
This problem is a bit mysterious, given that some users appear to be ok,
yet this one user is problematic. In your original post, you mentioned
haging for "several seconds". What's several? I'm wondering if there's
some (unexpected) data that's causing a problem, especially given the
apparent disparity with quota that you also mentioned. I think I'd dig
around in that area to see what turns up.
