Troubleshooting external -> My company e-mail

[Marlon Brown]

A VIP user claims that he is sending e-mails from his home address
mym...@myfamilydomain.com to his company mailbox. He claims that all e-mails
sent from that domain does not get delivered.

As far as I know the Exchange AV is not configured to block
'myfamilydomain.com'. I look the logs of the Exchange AV and see no reports
there of quarantine messages related to @familydomain.com.

What else could I do troubleshoot this type of scenario ?

sends the message.

If you're not seeing the message in the SMTP Protocol Log then it's
never getting to the Exchange server. If that's true then the problem
lies between his SMTP server and yours.

Sorry I did not mention before:
He claimed he's got no NDR at all. That's what makes difficult to me.

Another question:
Should I enable SMTP logging on the SMTP connector or mailbox server ?

Send a message to the Exchange Server from that address via Telnet. That
will verify whether or not Exchange is able to receive mail from that
particular domain. If Exchange is able to accept the mail, then the issue is
outside of Exchange. The problem could be on the senders end. The article
below contains the steps to send a message using the Telnet utility. In the
MAIL FROM: field enter the domain the user is send from
(mym...@myfamilydomain.com).

Start with the gateway SMTP server.

That's why I said to have him ask for a delivery receipt.
