Thanks for the answers. About domain name - the thing is that right now i see exactly the next message (except ip address) "Received: from mail.localdomain ([ip.add.re.ss]) by mx.google.com..". And "mail.localdomain" is a local alias. So, it cant be resolved from external network. So, it cant depend from real ip address. So, only postfix can say to mx.google.com that postfixbox is "mail.localdomain". And i think postfix says it's $myhostname here. I understand that it is really not a big thing, but i just would like to use respective domain names for this, if there is a way.
About message id - i understood i can place message id in php. but we have several domain names. Sometimes several scripts at everyone (like forum, support ticket system, main script, etc). Sometimes it is third-party scripts. And every script can have more then one place where it sends email. I would prefer to change message-id at postfix side, if there is such way. if somebody has any ides how to do any of this things with postfix, please, let me know. thanks, Andrey. 2012/9/23 Noel Jones <njo...@megan.vbhcs.org> > > On 9/22/2012 9:41 AM, Андрей Клаус wrote: > > 1) At webserver postfix generates a message-id field.
