Sounds great but doesn't that mean I need exactly one unique public IP for
every domain? If I 'skip' the PTR records completely how likely is emails
Hi,
if I want to use several domains on my Postfix server do every domain need
a unique PTR DNS entry to an unique IP or is it enough to setup $myhostname
to the main domain?
smtp_helo_name = $myhostname
smtpd_proxy_ehlo = $myhostname
Greetings
