Emails sent without originating IP - pixelbat - 09-15-2015
So, basically I have two servers, both running Sentora. The main one is serving up websites and our forum. I've got it behind Cloudflare because of DDoS threats/activity. Unfortunately, that doesn't protect our IP from outgoing emails generated from our forums. The second server is a small VPS I've been trying to set up to function as a SMTP for our outgoing email. I pretty much got it all to work, except one thing... It's passing on the IP in headers from the first server.
I'm not super experienced with all this. It's mostly been a learn-as-I-go-along situation. In fact I spent hours trying to make this work sans-Sentora and just installing Postfix and trying to config it. I couldn't get anything to work. It wasn't until I installed Sentora on the second server did I finally get emails to come through, except with an IP trail. I guess my question is... Is there a way for me to make my Sentora acting as our SMTP relay to omit the originating IP? I've read a few things about editing Postfix main.cf but I'm pretty confused because the cf Sentora makes has so much more going on.
Any ideas or suggestions are greatly appreciated. Thank you

Finally figured it out. If anyone ever runs into the same scenario as me, this did the trick...
