clamscan has a purpose. As others have also said - YMMV. A very lightly loaded mailserver (~100 msgs/day) shouldn't have a lot of problems with clamscan. At least not with the 0.88.x version. Besides, mimedefang uses clamscan in case a zip file comes in that clamd is unable to scan, because it is packed with the deflate64 method, which clamd cannot handle. In that case "clamscan --unzip" is called to scan the file again (at least - clam cannot handle deflate64 up until at least 0.90.3, I haven't checked 0.91rc1 yet). So for anyone upgrading clamav from 0.88.7 to 0.90, the sudden massive drop in performance (about 50% slower scan times, 10-20 times slower startup times for clamd and clamscan) would come as a surprise. The release notes of the 0.90 version of clamav unfortunately fail to mention that performance problem. (To be fair - the scan times have been fixed since 0.90.2 (or 0.90.3 for some platforms), and the startup time appears to be fixed in 0.91rc1. Kudos to the delopers for recognising one of the roots of all evil). So I don't think it's mimedefang that should label the clamscan method as "not for production use". -- Jan-Pieter Cornet <[EMAIL PROTECTED]> !!
