mail host name problem

Hello

When i receive read mail or view source of mail writes like this

Received: from localhost (localhost [127.0.0.1])
by server.rootdomain.com (Postfix) with ESMTP id 936BD7E039C;
Wed, 9 Mar 2011 08:52:05 +0200 (EET)
can i change hostname server.rootdomain.com to clients domain
(like this for client1.com mail.client1.com)

Thanks for your help

 

No, Postfix uses the hostname that is set in myorigin in /etc/postfix/main.cf.

 

Thanks for your help

i wanna ask something,if i change hostname in myorigin (for example xxx.domain.com) is it problem for mail receive and send. (orginal host name is yyy.anotherdomain.com)

 

No, but make sure the new hostname exists in DNS.

 

Thanks Falko
