On CiviCRM 4.5.5, I have an email address of [email protected] configured under Administration > Communication > From Address.

When I send the test email the reply to address is the correct email address.

However when I sent a membership renewal reminder the address is a random set of letters and numbers viz:

Return-Path: <[email protected]>
Reply-To: <[email protected]>
From: "APMA" <[email protected]>
To: "Paul Murdoch" <[email protected]>
Subject: [CiviMail Draft] Your APMA membership
Date: Sun, 14 Jun 2015 20:27:25 +1000
Message-ID: <[email protected]>
MIME-Version: 1.0

I am guessing this has to do with the automated tracking of newsletters or similar. However I would like the reply to email address to be [email protected].

How do I debug, track this down and correct this?

Testing this on v4.6.3, you can define the reply address for a scheduled reminder by editing it at Administer > Communications > Schedule Reminders (civicrm/admin/scheduleReminders). Check if you can configure it there first? I've tried a scheduled reminder just now and see the expected email address when I receive it.

The "random set of letters" is a feature called Variable Envelope Reply Path ("VERP") which permits CiviCRM to better identify and track bounces, unsubscribes and other mail system errors by having them "return" to a unique, identifiable email address.
