Postfix: how I set outgoing IP address

SilentWarrior

Basic Pleskian
Hi,

I found no way to set the outgoing address for emails. Plesk is configured with more then one IP.
I like to send all emails from one IP (because this have a FQDN) and I should change the Helo message to the FQDN.

Can I just edit the main.cf of Postfix or will Plesk overwrite this changes ?

Thank you
 
Yes, I read that already.

But I'm confused about the meaning of "independently install Postfix"
Atm I use the postfix installed by plesk. So I ask me what's happen if I do this command.
 
All should work for you if all mentioned conditions are satisfied.
