some of them having up to 30000 emails

With outlook express I have some problems now and then that get fixed
by doing a "clear local cache" on OE. Only once had a problem with
thunderbird (started constantly complaining that it could not save the
email it just sent to the INBOX folder while at the same time it HAD
saved it). Worked around this annoyance and didn't try to fix it

The main gotcha with Courier, is that by default it only allows 4
connections per IP, but T-bird tries to make 5. You can fix that in
either place (probably the server if you have lots of users).

I've change the number of connections from a single IP to 75, especially
when running X-Terminal supporting 10+ people at the same time. Usually
it just works otherwise. The only thing I have to change is causing
exim4 to use $HOMEDIR/Maildir delivery vs. /var/spool/mail.

And this bit about not being able to handle large amounts of mail?

greg@uno:~$ du -ks Maildir/
313998560 Maildir/

All served up via courier-imap-ssl. Hope that clears it up.

Also, I've scaled courier-imap upto ~700 users with ~100 continuous
users accessing, using a single processor with 4G of memory, a single FC
SCSI card to a SAN.
