Yes it did. And it appears that this is the reason: Mime-Version: 1.0 Content-Type: multipart/signed; micalg=pgp-sha1; protocol="application/pgp-signature"; boundary="H1spWtNR+x+ondvy" Content-Disposition: inline Andrew's is like this: Content-Type: multipart/signed; boundary=Apple-Mail-1-746495031; micalg=sha1; protocol="application/pkcs7-signature" Mime-Version: 1.0 (Apple Message framework v924) Date: Tue, 10 Jun 2008 16:23:32 -0400 References: <8DFCF30B986212E9F5E6DE8E@utd65257.utdallas.edu> X-Mailer: Apple Mail (2.924) X-Spam-Scanner: SpamAssassin 3.000004 (http://www.spamassassin.org/) on batman.cs.uoguelph.ca X-Spam-Score: hits=0.0 X-Spam-Level: X-Spam-Tests: FORGED_RCVD_HELO,SPF_PASS X-Spam-Status: Suspected X-Scanned-By: MIMEDefang 2.63 on 131.104.94.198 X-Scanned-By: MIMEDefang 2.52 on 172.17.94.85 X-Content-Filtered-By: Mailman/MimeDel 2.1.5 Notice that his was processed through MIMEDefang twice and then Content Filtered by Mailman. Also, his content type is protocol="application/pkcs7-signature" whereas yours is "application/pgp-signature". There's also no Content-Disposition: line in Andrew's email headers, so it's possible that absence of that line makes a difference as well. By default, it appears that Mailman does not do content filtering. It also has pass rules (if filtering is enabled) for multipart/mixed, multipart/alternative and text/plain. So, it's possible that MIMEDefang is the culprit instead. -- Paul Schmehl As if it wasn't already obvious, my opinions are my own and not those of my employer.
