IMAP Broken, Firewall Not Blocking Port, User/Pass Correct


Oct 10, 2005
I'm unable to get at my imap server through telnet or Outlook Express, and yet /webmail is functioning normally. Although only one user is really affected, I would like to clear this problem up before it spreads as more people use the server. Here is the error Outlook Express gives:
Header download for the 'Inbox' folder did not complete. Could not select 'Inbox' on the IMAP server. You might try refreshing your folder list to synchronize with the IMAP server. Account: 'John's SF Mail Service', Server: '', Protocol: IMAP, Server Response: 'The server did not respond to this IMAP command before the connection was terminated.', Port: 143, Secure(SSL): No, Error Number: 0x800CCC0F
I'd be really grateful for any help that can be offered. Thanks.
