Okay I set myhostname = gateway.aus-city.com Now it replies properly, bit it still fails RFC, I get this now (it's better as atleast now the name exists not a unknown server) mail.aus-city.com claims to be host gateway.aus-city.com but that host is at 202.129.79.106 (may be cached) not 203.206.129.129 smtp_helo_name = mail.aus-city.com assuming, 203.206.129.129 is the outgoing IP. if you have multiple outgoing IPs, just live with that. most people won't check this (unless you server has a bad reputation that causes additionnal/aggressive checks). There are 28 domains on the server all on individual IPs. when it comes to email, all domains can be served with one IP. so if 203.206.129.129 is the outgoing IP, use it for all these domains (for smtp I mean). the alternative is to run one postfix instance per IP/domain, but that's a lot of work (and may be tricky). Any solution or live with it? I assume it's much better having a real name rather than a non existent one?
smtp_helo_name ignored
I am running postfix on my mail server. The server uses a domain name in my local DNS that does not exist. So to comply to RFC I used the smtp_helo_name = real.name.com In my main.cf file. But it does not work dnstools still reports that the helo is answering with the hostname, not my entry in main.cf so somthing is taking preference. How do I fix this I simply want the helo to respond with what I specify and it will comply. Thanks! Sent from my iPhone

Re: smtp_helo_name ignored
Hi Sahil, Yes exactly! So I should be using smtpd_helo_name to set the server helo name? Thanks!

Re: smtp_helo_name ignored
Hi Noel, I will send you the logs tonight re the bounces. Okay the helo is this correct? smtpd_banner = gateway.aus-city.com I want the helo to say that name. I assume I drop the hostname and what about the ESMTP? Thanks!
