we've debated in-house whether it should be
an host or a cname but never found any concrete difference is why I
asked.

IMail it is less of an issue having the mail server publicly
available.

no it would not need an MX In fact it shouldn't have
one just an "A" record if it is going to be publicly accessible (not the
best idea)

DNS confusion...
If I have a domain, example.com, with an MX
record that points to mail.example.com, is there a reason that
mail.example.com would *also* need an MX record? Would it need
on if mail.example.com has an IP address with a valid PTR? Does
this make sense?
