[popa3d-users] Suddenly, won't authenticate

[James R. Mirick]

I've been running popa3d on Red Hat EL for almost a year.  One morning, I extract my emails from the server (running PostFix) and everything's fine.  Then, later in the day, I get an error (T-bird says a password error) and can't get to anything.  Nothing else has happened on that server, its running shared files via samba and that's all. I can log onto the machine with the email IDs and passwords, so the operating system accepts these accounts as valid. NMAP shows port 110 is open. I can do 'telnet linux2600 110' and it responds +OK.  USER command elicits +OK also, but PASS fails: it just says '-ERR' and dumps me back to the command line, says "connection closed by foreign host." When I look in the log, I see the following (for this example I had just gone to the console and stopped and started popa3d just to be sure): Jul 12 16:44:55 linux2600 popa3d: popa3d startup succeeded Jul 12 16:47:44 linux2600 popa3d[3369]: Session from 192.168.10.100 Jul 12 16:47:44 linux2600 popa3d[3369]: Authentication passed for jrm Jul 12 16:47:44 linux2600 popa3d[3369]: Failed or refused to load /var/spool/mail/jrm This makes me think there's something corrupted in the mail files, but the fact that it won't accept a password (for my account or any other) makes me think its authentication. I completely rebooted the server, no change in behavior. These mailboxes ARE accepting mail, so PostFix can access the mailboxes. Thanks in advance . . .
