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.
Host Points To TTL webmail 12.345.789.101 14400
mail webmail.d.com 14400
0 @ mail.d.com 14400
I've created an email account on hostmonster, firstname.lastname@example.org: 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?
