Julian & Miguel,

thanks for your answer. The average size was calculated by other people.
Today i did a little research, and came with a more accurate average size:
60 KB.

The email traffic of the network is splited through different SMTP servers,
so i think that with two or three boxes we'll solve the problem. According
to Miguel's message, a dual-CPU 2.4GHz Xeon with 2GB ram and SCSI disk will
virus-scan over 1,000,000 messages per day.

Maybe with 3 boxes running a similar configuration we'll be fine, right?
It's a little expensive, but the only solution if we want to use
MailScanner+AV to analyze such huge traffic.

What do you think?
