[Show Quoted Text - 12 lines][Hide Quoted Text] Could you send me a signed message directly? done Works fine here. PHP error logging is returning nothing? Do you have a memory limit set? Strange... memory_limit = 32M I really wonder why the unsigned message with the sam attachment works fine forgot to say that there is nothing in the apache logs...

But there is still a Problem, when I send (using IMP) the same zip file once PGP signed and once without signing. In the first case it is not possible to open or download the zip file with IMP again. I just get an empty window. Have you verified that IMP is not still attaching the message as a text/plain part? It seems to be attached in the right way, see the source below: [....] From: Rieder Dietmar <dietmar.rieder@tugraz.at> To: Didi Rieder <dietmar.rieder@tugraz.at> Subject: test MIME-Version: 1.0 Content-Type: multipart/signed; boundary="=_3hkevx5mv3y8"; protocol="application/pgp-signature"; micalg="pgp-sha1" Content-Transfer-Encoding: 7bit User-Agent: Internet Messaging Program (IMP) H3 (4.2-cvs) X-Organization: Graz University of Technology X-Originating-IP: 129.27.145.220 X-Scanned-By: MIMEDefang 2.52 on 129.27.3.25 X-Scanned-By: milter-sender/1.8.900 (mail [129.27.3.25]); Tue, 28 Mar 2006 23:51:44 +0200 X-Scanned-By: MIMEDefang 2.52 on 129.27.10.18 This message is in MIME format and has been PGP signed. --=_3hkevx5mv3y8 Content-Type: multipart/mixed; boundary="=_5rlbusehyps0" Content-Transfer-Encoding: 7bit This message is in MIME format. --=_5rlbusehyps0 Content-Type: text/plain; charset=UTF-8; DelSp="Yes"; format="flowed" Content-Disposition: inline Content-Transfer-Encoding: 7bit test -- ___________________________________________ D i e t m a r R i e d e r, Mag. dietmar.rieder@tugraz.at \| PGPKey ID: 3431D0B0 http://genome.tugraz.at Tel: +43 316 873 5339 - Fax: +43 316 873 5340 --=_5rlbusehyps0 Content-Type: application/zip; name="papers.zip" Content-Disposition: attachment; filename="papers.zip" Content-Transfer-Encoding: base64 UEsDBAoAAAAAAGOLfDQAAAAAAAAAAAAAAAAHABUAcGFwZXJzL1VUCQADyVUpRNxVKURVeAQA9AH0 AVBLAwQUAAAACAD0stYwly/TBUi+BQAZAwYAFgAVAHBhcGVycy9pYm9ycmEtMTk5Ni5wZGZVVAkA A0yV2ECisOBDVXgEAPQB9AHE/AVUHcvWNgovHBKc4LZwEhwW7g6BoMHd3T24BAnu7hrcXYMHd3d3 d7tkn7P3Pufsc/f3ve+4//jXGIzunt391KxZc1bNeqpoMhkhERoGWkYEsvWNkQmENyxMQHqgla4p AhcXEIFO0sTSQMfW5IuBPpDh9VIayML6ehADqgEZGFlAQCZWdqDGr8eATOwgenr211NhIBuI8ddD UkAG+tfD59dbjCxMr2/z8AARDCz1f2ED/5c/Z1sDQ4RXDZleS6L/54+BBfjbEWj5u4yBgZHtLzLG 16u/yBjZ/yJjATH9RcYG+iseO9Nf3mWkZ/pLGYwMjAx/kTEy/FXGRM/4Vxn7X58Dsf1Vxsz613JZ WP4qY2X+q4wN9Fc8dqa/yF7V+4t+TK+G/ovs1Qh/lbGD/iJjYvtLuzGBWP8qY371uP+UsTD/Vcb6 1zZiYmP6q4z9r7qA/ks9Xn34L2WAmNj/gsfK9te2ZGVj+osNWNmZ/lI3Nnr6v8oY/mrn30LtP2Us /+pX9rY6JuYGtq8xi0An/xqtr6HHiEAnbmloBWR5hQPKvQainJWVPfAX0G9XMrYGjr9FJuOvuBYX [...] Here is the same attachment sent without signing: [...] From: Rieder Dietmar <dietmar.rieder@tugraz.at> To: Didi Rieder <dietmar.rieder@tugraz.at> Subject: test 2 MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="=_5dltnmb2cx8o" Content-Transfer-Encoding: 7bit User-Agent: Internet Messaging Program (IMP) H3 (4.2-cvs) X-Organization: Graz University of Technology X-Originating-IP: 129.27.145.220 X-Scanned-By: MIMEDefang 2.52 on 129.27.3.25 X-Scanned-By: milter-sender/1.8.900 (mail [129.27.3.25]); Tue, 28 Mar 2006 23:57:26 +0200 X-Scanned-By: MIMEDefang 2.52 on 129.27.10.18 This message is in MIME format. --=_5dltnmb2cx8o Content-Type: text/plain; charset=UTF-8; DelSp="Yes"; format="flowed" Content-Disposition: inline Content-Transfer-Encoding: 7bit test 2 -- ___________________________________________ D i e t m a r R i e d e r, Mag. dietmar.rieder@tugraz.at \| PGPKey ID: 3431D0B0 http://genome.tugraz.at Tel: +43 316 873 5339 - Fax: +43 316 873 5340 --=_5dltnmb2cx8o Content-Type: application/zip; name="papers.zip" Content-Disposition: attachment; filename="papers.zip" Content-Transfer-Encoding: base64 UEsDBAoAAAAAAGOLfDQAAAAAAAAAAAAAAAAHABUAcGFwZXJzL1VUCQADyVUpRNxVKURVeAQA9AH0 AVBLAwQUAAAACAD0stYwly/TBUi+BQAZAwYAFgAVAHBhcGVycy9pYm9ycmEtMTk5Ni5wZGZVVAkA A0yV2ECisOBDVXgEAPQB9AHE/AVUHcvWNgovHBKc4LZwEhwW7g6BoMHd3T24BAnu7hrcXYMHd3d3 [...] This opens/downloads correctly, whereas the signed one just returns a blank page.

I just get an empty window. Have you verified that IMP is not still attaching the message as a text/plain part? This obviously won't work if the zip part is still being sent as text/plain in Q-P as we (on purpose) don't send Q-P data binary safe. See e.g. ~~Bug 3565~~. This works absolutely fine for me (the zip file is being attached as application/x-zip-compressed and being sent base64 encoded).

The browser is sending the wrong mime type for the zip file (text/plain). Ok (will have to find a solution for that, Firefox Solaris) But there is still a Problem, when I send (using IMP) the same zip file once PGP signed and once without signing. In the first case it is not possible to open or download the zip file with IMP again. I just get an empty window. Just in case. I attach the file with which I tested the scenario....

zip file attachments (and maybe others) get broken when messages are sent signed by PGP or S/MIME at least it is not possible to open/download them with IMP again. hmmm... and my users are reporting that it doesn't work when not signing. here is an example of a test mail I recieved from them: [....] Subject: Test MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="=_11edkqj6am74" Content-Transfer-Encoding: 7bit User-Agent: Internet Messaging Program (IMP) H3 (4.2-cvs) X-Organization: Graz University of Technology X-Originating-IP: 129.27.6.3 X-Scanned-By: MIMEDefang 2.52 on 129.27.3.25 X-Scanned-By: milter-sender/1.8.900 (mail [129.27.3.25]); Tue, 28 Mar 2006 11:24:47 +0200 X-Scanned-By: MIMEDefang 2.52 on 129.27.10.18 This message is in MIME format. --=_11edkqj6am74 Content-Type: text/plain; charset=UTF-8; DelSp="Yes"; format="flowed" Content-Disposition: inline Content-Transfer-Encoding: 7bit Test mit UTF-8, ohne S/MIME Reinfried --=_11edkqj6am74 Content-Type: text/plain; charset=ISO-8859-1; name="test.zip" Content-Disposition: attachment; filename="test.zip" Content-Transfer-Encoding: quoted-printable PK=03=04=14=00=00=00=08=00=C3Z\|4=9C=B6=15 =FF=07=00=00=1A.=00=00=0F=00=15=00test/mnenhy.rdfUT=09=00=03=3D=00)D=3D=00)D= Ux=04=00=E9=03 [.......] So it seams, that the attachment does not get encoded in the right way.
