This is how Postfix identifies itself in the SMTP server, the SMTP
client, and in the "sorry I could not deliver your mail" messages.
See also: http://www.postfix.org/BASIC_CONFIGURATION_README.html
Note: some SPAM filters will be friendlier if this name matches
your IP address. But there is no law that requires this.This is not required for your server.
> 3) MX record in public DNS
Note: some SPAM filters will be friendlier if you have an MX
record that resolves to your myhostname and IP address. But
there is no law that requires this.
See http://www.postfix.org/BASIC_CONFIGURATION_README.html for many
questions related to the ones that you were asking.
