For better protection, I would like to remove this - however - I am
not sure if all ISP's email servers are willing to accept emails from
arbitrary sender email addresses. I suspect not all will like this -
The domain of the MAIL FROM address must exist. And since there are mail
servers doing callbacks via SMTP, the MAIL FROM address should accept mail.
so - is there a standard I can use?
MAIL FROM: <> maybe?
MAIL FROM: postmaser maybe?
MAIL FROM: postmaser(_at_)real-senders-hostname maybe?
MTA's doing SES will not accept MAIL FROM: <> to a non-signed address.
And some of them probably neither MAIL FROM: <postmaser> or
MAIL FROM: <postmaser(_at_)real-senders-hostname> to a non-signed address.
