-------- Original Message -------- Subject: logging attachement hashes (05-Nov-2013 12:53) From: Andreas Schulze via amavis-users <[email protected]> To: [email protected] Hello, I wrote a patch to enable amavisd logging a hash of each mimepart of a message. As a result we have a nice logging about attachment with randomized names: Nov 5 13:24:34 amavis amavis[63605]: (63605) p003 1/2 Content-Type: application/zip, size: 175613 B, md5: e687fa20dbe2f62418da7dee62f5ef74, name: VodafoneWillkommen_915348761926.zip Nov 5 13:24:47 amavis amavis[64401]: (64401) p003 1/2 Content-Type: application/zip, size: 175613 B, md5: e687fa20dbe2f62418da7dee62f5ef74, name: VodafoneWillkommen_246684491810.zip Nov 5 13:24:49 amavis amavis[37512]: (37512) p003 1/2 Content-Type: application/zip, size: 175613 B, md5: e687fa20dbe2f62418da7dee62f5ef74, name: VodafoneWillkommen_385492343722.zip Nov 5 13:25:11 amavis amavis[23929]: (23929) p003 1/2 Content-Type: application/zip, size: 175613 B, md5: e687fa20dbe2f62418da7dee62f5ef74, name: VodafoneWillkommen_410730648345.zip Nov 5 13:25:28 amavis amavis[23927]: (23927) p003 1/2 Content-Type: application/zip, size: 175613 B, md5: e687fa20dbe2f62418da7dee62f5ef74, name: VodafoneWillkommen_067966022207.zip Nov 5 13:25:35 amavis amavis[23931]: (23931) p003 1/2 Content-Type: application/zip, size: 175613 B, md5: e687fa20dbe2f62418da7dee62f5ef74, name: VodafoneWillkommen_886327295193.zip Nov 5 13:25:49 amavis amavis[23923]: (23923) p003 1/2 Content-Type: application/zip, size: 175613 B, md5: e687fa20dbe2f62418da7dee62f5ef74, name: VodafoneWillkommen_079214708084.zip Nov 5 13:25:58 amavis amavis[23936]: (23936) p003 1/2 Content-Type: application/zip, size: 175613 B, md5: e687fa20dbe2f62418da7dee62f5ef74, name: VodafoneWillkommen_381806514856.zip Looking at these logs it's very easy to identify malicius content still not detected by virusscanners. Maybe somone has an idea to extend that feature.
