This is all that is necessary to be a legit mail server. What most
people do however, is setup their "personal" email server at home and
do not do any of the above; then complain about others not trusting them

If your ISP is co-operating with you on DNS PTR records then you must not
be violating the service agreement. Most ISP's however do not allow
"home" users to run any server of any kind without violating the service
agreement.

Also, a BIG note here is that you have a static IP address, not a
dynamic IP address.

You don't need to, you already are with your ISP.

I don't think you are penalised. However, if someone won't accept your
email, that is their choice.

Not at all. This is just a request that people who run servers follow
the RFC guidelines ;)

As a last note, I stated LONG* ago that we could clean up most problems
just by having the big 3 or 4 mail services (Google, Hotmail, Yahoo, etc.)
only accept connections and messages from servers who match the SMTP HELO,
DNS A, and DNS PTR data (or valid IP Literal in SMTP HELO), as well as
enforce
actual message standards, at the very least, for the message headers, such
as forcing the DATE and "SENT FROM" headers that all messages are required
to
have. That would force all of the knuckle heads who refuse to do this on
their own to comply, and allow the rest of us to reject at those who do not
comply and not have to hear about "well my mail works every where else...

Cheers!
