Is Hotmail in the habit of ignoring MX records?

One of my users has reported incoming mail failures, which I finally
tracked down. It turned out that Hotmail has seen fit to send the mail
to his domain's A record machine, despite the fact that he has valid MX records.

The A record points to my webserver, which does not normally accept mail
for anyone. The mail server MX records are to an entirely different machine.

Comments?

Do I need more valium?
