Hi guys,

First, thanks a lot for the interest in this thread.

i remember some times on the samba-list, when some worms where around, i 
had about 75 viruses PER HOUR. And they did not filter anything....

so, i do my very best to answer all your questions:

1) i don't use clam, i use antivir (h+b edv)
2) the machine is a old p3/866 mhz with 128 mb ram only, running fc3 (a 
granny machine...)
3) mail quantity is about 300-400 per day. Average use is according to 
tload between 0.90 and 3.50 (peaks) avg about 1.3 *ouch*
4) spamassassin is running as daemon (3 childprocesses)
5) amavisd-new is running as dameon (3 childprocesses)
