It is the documented method, it works perfectly on *my server*, that is my
disclaimer. I have for each domain I host, shared IP or not:

A Record:  domain.xxx -->  ip address
A Record:  www.domain.xxx -->  ip address
MX Record: domain name field: domain.xxx
           mail server field: www.domain.xxx

Also, since my dns server names are different than the default, I change my
SOA records to the reflect proper values.

On both of my A Records I have a reverse pointer, as per documentation.
Don't know if it is needed or not, never tested without it.

I have an entry as above for EVERY domain I host, no matter if shared or
solo domain for ip, every domain gets an entry.

As written about, I have one MX record with domain.xxx --> www.domain.xxx
(mail server).

I agree with no one, we just may share the same opinion.

I've been a programmer/support-geek for over 20 yrs, I am always careful in
my posts. If I am questioning shared advice I would note it. It is up to
forums like this to correct incorrect posts - as your's at least questioned
mine. It made me re-look at my DNS to be sure that all understood what I
was attempting to say and not have it misinterpreted.

The above is how my well-running system is setup. Comments/corrections are
always welcome :)
