Timo, Here's an example of the filesystem quota issue: A user was near his hard filesystem quota, so he moved some junk to his Trash folder to clear disk space. He got the following error on his IMAP client:

"Internal error occurred. Refer to server log for more information. {2006-04033 11:08:44]".

My setup: Solaris 9, beta3 (soon going to beta4), mbox format, IMAP only. Home directories (where IMAP folders and index files go) have filesystem quotas.
