[svlug] Problems connecting to pop3 - more info

[Skip Evans]

Regarding the previous message showing the details of the pop3 problem, 
here again is what happens connecting to the port (or with PASS used per 
Bill's comment):

sevans at linux1:~$ telnet 207.234.129.112 110
Trying 207.234.129.112...
Connected to 207.234.129.112.
Escape character is '^]'.
+OK POP3 207-234-129-112.ptr.primarydns.com 2004.89 server ready
USER *****
+OK User name accepted, password please
PASS ********
-ERR Bad login

But I can connect to the standard telnet port, with the same user name 
and password:

sevans at linux1:~$ telnet 207.234.129.112
Trying 207.234.129.112...
Connected to 207.234.129.112.

You have mail.

Where should I begin looking for differences to determine
how telnet is authenticating the user differently than pop3?

Or am I on the wrong track? Right now, I am trackless.
