I am facing an issue with the DKIM setup. We are sending newsletters which are going to spam in gmail. The dkim & spf passes. Even the reverse dns is setup properly. Below is a copy of mail headers that I see in gmail.

I Think so the Received: (from abc@localhost) is causing the issue.
What I need to know how to resolve it. Instead of localhost it should use mydomain.com This is my first time setting up such kind of server.
This may be the problem with the envelope sender and from address because,an email has two addresses associated with sending it: the envelope sender, and the From: address. The envelope sender is where computers should respond (in the case of bounce messages or errors); the From: address is where people should respond. In most cases, the envelope sender and the From: address match.Some case the Gmail put the mails which the 2 sender field did not match. You may try with the same.
