Hi,
I'm trying to achieve the following:
1. Forward all incoming mails to my Gmail account via virtual alias. This is the guide:
Setup mail forwarding in postfix on Ubuntu or Debian.
2. Send all outgoing mails via Gmail SMTP server. This is the guide:
Configure Postfix to Send Mail Using an External SMTP Server.
The problem is that I can have only one of them but not both.
If I use Gmail SMTP, then all incoming mails get their original address overwritten like this:
"<Somebody Name>
somebody@example.com" => [Postfix at my host] => "<Somebody Name>
myuser@myhost.com" (in Gmail inbox)
Is it possible to configure Postfix, so it leaves forwarded e-mails intact and adds "myhost.com" only to mails, which originate from myhost.com?
Thanks.
This is my /etc/postfix/main.cf file:
