CiviCRM Community Forums (archive)

I thought I had everything working. Cron jobs functioning, accounts setup (I think). I have reviewed the steps in the manual and help screens repeatedly.
(I have attached a screen shot of my email setup)
civiCrm 3.2.1

My mass mail goes out nicely.

I set the return address as xxxxxxxxxbounces@gmail.com  (xxx = name of organization)

HOWEVER, when I view the headers of the email, I get this:

Reply-To: r.35.177.34995b44c722aa00@gmail.com
Return-Path: b.35.177.34995b44c722aa00@gmail.com

Where do these weird email addresses come from?
