Try posting with examples of what you tried, which clients you tested. Did
you check to see if it was listening on the right port. What error messages
are you getting. Run it through a proxy or packet sniffer or learn the POP
commands and try it using telnet. Go read Eric S. Raymonds 'How to ask
questions...'

POP used to use clear text passwords - very insecure. I'm not very familiar
with RH., but its likely that cleartext auth is disabled.

Why did you telnet localhost? Surely you should be telneting your POP3
mail server?

e.g. telnet mail.garbage.uk 110

Once you did that, you need to enter at the command line:

user fred RemoveThis @garbage.uk

then

pass [your password] (without the brackets)

Should then be connected to your POP3 server, and you can use LIST RETR
DELE, etc, etc...

Sorry about the other response - just killfile him.

No, you should seriously consider reading _everything_ that Eric has
written.

And yes, YES - I know I'm posting from Windoze!!

Thanks for yur reply.

First, I am trying to set up POP3 on a Red Hat Fedora Core 3 machine

I was using "Linux Troubleshooting Bible" by Christopher Negus.

ON page 508, here is what he says to do :

telnet localhost 110

When you get acknowledgment , enter "user .. my name"

The returning prompt is "OK username accepted, password please"

I enter my password and get the message

"ERR Unknown AUTHORIZATION State Command"

I tried your method, but I get the same ERR message.

What is strange is when I enter the same commands on my Red Hat 9
machine
where POP3 DOES work, I get the same error message - but I can use POP3
just fine to get my mail to my workstation.

POP3 files are installed in the following locations

/etc/xinetd.d/ipop3
/usr/sbin/ipop3d
/etc/pam.d/pop and /etc/pam.d/pop3

Any help would be appreciated.

Did you just enter your password alone or did you enter the command
"pass" (without the quotes) followed by a space followed by the actual
password?

The latter is correct. The former will cause the server software to
attempt to interpret your password as a command.
