  (*) I'm somewhat confused here, the Email and Web server aliases were
set to company.com above. I have assumed that the MX Record would also
point to company.com, and all my records are setup that way. Some of my
clients use 'mail.company.com and their MX records point to
mail.company.com, having little to do with the name of the site.

I assume from your interpretation that the MX record should point to the
name of the site, and has nothing to do with the email server alias.
