I am helping a friend with his website, and am having a problem with his webmail configuration, which I suspect is due to a misconfigured MX record.

His domain is registered and hosted by hostmonster, they have a webmail option.

A record:

Host    Points To       TTL

webmail 12.345.789.101  14400

CNAME:

mail    webmail.d.com   14400

MX Record:

0   @   mail.d.com  14400

I've created an email account on hostmonster, [email protected]: however, when I sent an email to this account, it appears to be routing to /dev/null. I know that it's not actually, but am unsure of the steps I can take to track this down?

I've tried using dig, but am unsure where to start. How can I track down where this email is being routed to?
