It seems to be working...

Yeah, there was a SELinux issue. I had reported this problem about a year ago with mimedefang + sendmail on Fedora... figured the fix got into CentOS SELinux as well, but it hadn't.

Running as "permissive" until that gets fixed (again).

Had to add in:

non_smtpd_milter = ...

into /etc/postfix/main.cf (and do "postfix reload", of course) to get the resubmission scanned. Then it worked.

Not thrilled about having 2 Received: lines, but what can you do; I could tweak resend_message_specifying_mode() to not add the synthesized header...
