[Mimedefang] $Sender Problem

[Kevin A. McGrail]

I'm running some tests on $Sender in my filter.  One of my logics ran 
awry today because I guess I was expecting the From: header value but 
instead got the Return-Path value.

For example, I had $Sender have this

<SRS0=77yxaW=JV=removed.com=sam at srs.bis.na.blackberry.com>


Here's more headers:


Return-Path: <SRS0=77yxaW=JV=removed.com=sam at srs.bis.na.blackberry.com>

This appears to be SRS http://www.openspf.org/SRS so that the email doesn't run afoul of SPS.

Luckily, my emails are going through a Sanitize routine so I should be able to seamlessly wedge a de-SRS routine into the mix.  That looks to point to something like http://search.cpan.org/dist/Mail-SRS/

Anyone ever run across this?
