You could inspect the mail log, that way you would know if the mail was
getting to you and being bounced.

Try

Login as root (su -)

cat /var/log/maillog | grep xxxxxxx

instead of the xxxxxx put in a phrase that would identify their server as
the sending server or you as the recipient. This will tell you if the logs
have any mail from them.

or

tail -f /var/log/maillog | grep xxxxx

this will tail the logs in real time as messages are being sent to our
server.
Then just get them to send you an e-mail and watch the screen to see if they
show up.

You could just use

tail -f /var/log/maillog

but on a busy server you might miss the log entry as you will see everything
scrolling past.

That should give you a starting point to work from, if you don't see the
mail at your server it's not your problem, if you do then at least the logs
should tell you what is happening.
