FreeBSD 2. postfix 3. avavis-perl, www.amavis.org 4. a-v scanner for FreeBSD mail servers, KasperskyLab.rom http://www.kaspersky.com/products.asp?tgroup=0&pgroup=3&id=34 a-v scanning is heavy slogging, (memory, CPU, disk i/o speed (RAID 1 + O is good), disk storage (incoming mail queue directory for mail tailback waiting to be scanned) can reduce the throughput of a good mail relay hub to just 10% or 20% of its non-AV-scanning capacity, esp if the SMTP traffic has lots of largish attachments.
