Changing hostname in message with mail options

[V.N.]

Hi,
I try to solve the problem with changing hostname to public name. I made it for helo and ehlo, but got stuck in message with mail options.


What setting defines format for this message? I need change ct-ms-sr-vmmg02..... to mx4....

Usually you just need to:
* set the short hostname (mx4) in /etc/hostname
* make sure that you have an entry for your fqdn and short hostname in /etc/hosts (for the ip of the system)
* set the domain part of the fqdn as search domain in /etc/resolv.conf
* run `pmgconfig sync --restart 1`

I hope this helps!

Can I have in /etc/hosts my real hostname? I really need it.
Thus I just need to change hostname in SMTP messages.

try it - I think the postfix config (which also yields the output you want changed) relies on /etc/hostname and /etc/resolv.conf only - but please verify for yourself
