yes - without real load...it all depends on tuning the box/environment.
amavisd/clamd/vexira (our second av scanner)/dspam dont get much mails
delivered because of our extremely strict postfix anti spam config
(mostily at the smtp level - BEFORE fully accepting the mail)...we block
around 90-95% of junk at the doors and let the other (resource
intensive) daemons/services do the final cleaning. also keep in mind
that we are talking about an inbound antispam/virus gateway - no
pop3/imap or stuff like that...drawback is: we cant integrate things
like full av/spam quarantine into this system - but on the other hand we
have an extremely low false positive rate (when it comes to
RBL`s/DUL`s/RHSBL`s etc. im real "picky") - and greylisting also helps
much (we use gld / http://www.gasmi.net/gld.html).
