Hiya, A lot of my users are getting timeout problems when they connect via IMAP(no problems at all on POP3). A search on Google review that Outlook's implimentation of IMAP is not perfect and leaves multiple connections open to the mail server. A quick workaround would be to increase the MAXDAEMONS and MAXPERIP variable of Courier-IMAP server. Any idea where this conf file is located? chrno
What's the exact error message? Anything related to this in the mail log? Does the firewall allow connections on port 143 (IMAP)?
