Okay, update to my problem. Due to suggestions, I have upgraded certain peices of software.
I am now running: FreeBSD 4.7-RELEASE Qmail 1.03_1 Vpopmail 5.3.9_1 SquirrelMail 1.2.8 Courier-Imap 1.5.3 All above programs have been installed from the ports tree in fbsd. Also due to suggestions, I have modifed the authdaemonrc file for courier-imap to the following: authmodulelist="authvchkpw authpam" I rebooted the server, and so far people are able to login, we'll see in about an hour if people can still continue logging in. Like I said, imap logins just fail after a certain amount of time. I'm also going to check if pop3 authentication fails as well. Thanks for all the suggestions, I'll keep you posted. Taylor Dondich
