Does not matter. > 2) /etc/postfix/main.cf > myhostname= 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. > 3) MX record in public DNS This is not required for your server. 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.
