I cannot telnet out to port 143 on my ISA 2004 server. (It times out) I get the following error in the App log. Server publishing rule [IMAP IMAP4 Server] failed because there was no valid network listener. For requests to reach the published server there must be a network relationship between the selected listener networks and the published server. Location 325.934.4.0.2163.213. For more information about this event, see ISA Server Help. I do have the listener setup. Derek
