Postfix Multi Domain Email Going to Spam

Question

I have read over the other post from other users on this site about this topic.

I think I see my problem but cannot figure out where to change it.

My configuration:

Really want that shirt

I think my problem may be this: Sent from my work PC

Received: from [172.16.4.XXX] (unknown [69.63.128.XXX])

and sent from my home PC:

Received: from [192.168.1.8] (pool-96-234-206-191.bltmmd.fios.verizon.net [96.234.206.XXX])

I am sending the email through Thunderbird, I'm not sure how to change to my domain name if that's what i need to do. If I send email from a php form thought my website it works fine.

Any guidance would be great.

Any advice on what I could add to get someone to respond? Is my configuration so far off that i need more help than can be provided or have i stumped the community? — Brian Curless, Mar 20 '15 at 18:25
I replaced your placeholder domains with `example.com` and `example.net`. See [What information should I include or obfuscate in my posts?](https://meta.serverfault.com/questions/963/what-information-should-i-include-or-obfuscate-in-my-posts) — sebix, Mar 21 '15 at 10:16

Solved my issue.

I still not sure why this worked however

I installed roundcube, configured it for both domains,

After that I was able to hit the sitename roundcube URL and sign in and send email to gmail without going to spam,
