But we're just talking about detected spoofed envelope senders, not
message headers. When I had this test in place, it caused no
problems with mailing lists, forwarded messages, etc.

The only false positive I saw was with confirmation messages from
fedex.com, which are legitimate and wanted but are (inexplicably)
sent with the recipient address spoofed into MAIL FROM.
