Hello all...

Before I begin, this is a NW 6.5 SP7 server with GW 8.0 HP1 running on it.

Over the years, we have on occasion had problems sending e-mail to some of
our clients. But, for the first time, if looks like something is wrong with
my GroupWise GWIA.

Take a look at this log: The names have been changed to protect the
innocent, the guilty and everyone else, too....

14:57:41 25D MSG 54434 Command: <client's domain>.net
14:57:41 25D MSG 54434 Response: 220 mail.<client's domain>.net ESMTP
14:57:41 25D MSG 54434 Command: EHLO <my e-mail server fully qualified>
14:57:41 25D MSG 54434 Response: 250 ok
14:57:41 25D MSG 54434 Command: MAIL FROM:
14:57:41 25D MSG 54434 Response: 250 ok
14:57:41 25D MSG 54434 Detected error on SMTP command
14:57:41 25D MSG 54434 Command: RCPT TO:
14:57:41 25D MSG 54434 Response: 550 or contact your ISP or mail server
operator.
14:57:41 25D MSG 54434 Command: DATA
14:57:41 25D MSG 54434 Response: 221 mail.<client's domain>.net
14:57:41 25D Building undeliverable message

When we send something to this client, we got a message that referenced the
URL
http://www.linuxmagic.com/best_pract...om_domain.html

From that URL, they say that incorrectly handled MAIL FROM: command is
something that spammers don't handle well, so they block it. My log above
has a MAIL FROM: command that is blank which causes the Detected error on
SMTP command.

I'm guessing that I need get the MAIL FROM: corrected.

Any ideas??

Thanks in advance.
