Switch from qmail-scanner to simscan http://www.inter7.com/?page=simscan Docs at http://www.qmailwiki.org/ We specifically wrote simscan to replace qmail-scanner because of high loads. We've seen systems with loads of 20 drop below 1. The problem is with loading perl (qmail-scanner) instead of a small C program (simscan). We run simscan with the QMAILQUEUE patch to reject viruses at the smtp level.
