May be a problem logging in as root. Make sure your mail users have regular login accounts on the server?

Its not root. I've seen the server in this case.

ITRC'ers, lets demonstrate how good ITRC is at this. I'm stumped.

Zero pts please.

I prefer dovecot, what is the authentication method that you are using? Can you share the pop3 pam related files located in /etc/pam.d

Same results dovecot. We're stumped and focused on the authentication issue.

pwck shows no problems.

Firstly, thankls for all the speedy reply and help.

OK. Thanks Vernon.

It looks like the problem was root. I have opened other accounts and can retreive pop from the server.

Now another question
The authentication process takes almost 20 seconds

Here is the output of /etc/pam.d/popa3d

auth required /lib/security/pam_stack.so service=system-auth
account required /lib/security/pam_stack.so service=system-auth
password required /lib/security/pam_stack.so service=system-auth
session required /lib/security/pam_stack.so service=system-auth

Can you help me out?

Some of my pop3 accounts take about 20 seconds to seem to connect; I always thought it was my spam filters churning away.
