This is just an FYI, not sure it can be fixed on your end. Mac OS 10.4 Mail.app IMAP users timeout when the 11th user logs in. Restart dovecot and all is good until you get to the 11th user again. Times out the whole system. I changed the 40 users that were using Mac OS 10.4/Mail.app back to POP and all is good. Do not seem to have the problem with Leopard or Snow Leopard users, Thunderbird on any platform, Outlook or Outlook Express on Windows XP. Did not have the problem with Courier-IMAP.
