I have found out through other sources that SA strips out the envelope-to header when it creates its new message when report-safe is turned on why in heaven does it do that???? Its not like SA needs to strip it out in order to change the message&.

This has been gone over a few times on the list, (please check the archives) but its not "stripping out" the Envelope-To header in particular, its creating a completely new message in place of the old one with none of the original headers.
I should point out that Envelope-To is not a standard header, its being added to the messages by your mailserver, and your mailserver happens to rely on that header after the message is filtered by SA, to know what to do with the message. This is due to the design of Communigate Pro and the way SA has been integrated into it, its not a bug in SA.
The short answer is that until someone reworks the script that integrates SA with Communigate Pro, you need to use report_safe 0 mode.
