Re: An A record is an MX record and is a missing MX....

There is one other situation where you need an MX record. If your domain
is foo.com and the A record for foo.com is _NOT_ the machine that accepts
mail for foo.com, you need an MX record pointing to the correct machine.
Often this will be mail.foo.com or smtp.foo.com.

This is always the case. MX records are only required if you want to have
more than one mail exchange servers to serve your domain, e.g. if you
want to have a secondary mail server as a relay if the primary server
goes down.

If you only have one mail exchange server to serve your domain, you don't
need MX records. An A record pointing to your mail server is sufficient.
