Have a POP3 user accesses via Comcast cable, able to receive, but can’t

Have following

SMTP server settings:
Allow VRFY commands: disabled
Act as SMTP relay for any host: disabled [SHOW LOCAL_DOMAINS lists hosts]
Validate sender's domain name: enabled
Allow percent-hacked addresses: disabled
CRAM-MD5 SMTP authentication: disabled
PLAIN SMTP authentication: enabled
Realtime Blackhole List check: enabled
RBL domains to check:

The user has a VMS account and the Outlook settings are correct for both
incoming and outgoing servers, with user name and password.

Running MX5.4 under loadbroker on 7.3-1 thru 8.3 tried turning on
debugging to see why the server was not accepting the outgoing message

%SYSMAN-I-OUTPUT, command execution on node FREJA
"MX_SMTP_DEBUG" = "TRUE" (LNM$SYSTEM_TABLE) %SYSMAN-I-OUTPUT, command
execution on node NORNS
"MX_SMTP_DEBUG" = "TRUE" (LNM$SYSTEM_TABLE) %SYSMAN-I-OUTPUT, command
execution on node HAFNER
"MX_SMTP_DEBUG" = "TRUE" (LNM$SYSTEM_TABLE) %SYSMAN-I-OUTPUT, command
execution on node ODIN

to look at the log files after attempting to send a message, but I didn't
find any new log files.

Any Ideas?

I suspect the relay settings aren't right, I think it needs to be enabled
and rely on authenication.

Comcast Cable Internet??? Nearly all of the broadband providers have put
blocks on port 25 to thwart SPAMmers. I'd bet that your user can connect
to their provider's (Comcast's) SMTP server but I doubt they will be able
to connect to yours.

Have the user try to TELNET to port 25 on your machine to see if they get
any response at all. I'll wager that they will not be able to because of
Comcast firewalling.

Not sure what I am seeing, TELNET to port 25 gives me a window, which echoes
back my keystrokes, but that is it. SSH to port 25 gives a dead window
