restricting process limit

[LeVA <leva@az.isten.hu>]

Hi!

I'm using spamassassin on my system (Pentium-MMX 233 w/ 160Mb RAM), and 
it works fine, if I get small amount of messages. But when I get a lot 
of messages, the ultra-fast 233MHz processor can not take it, and it 
gets very slooow.
My setup looks like this:

I have a 'spam' user, and I've set up postfix, to run a tiny little 
script as this 'spam' user. This script accepts messages thru the 
stdin, and it filters the message thru the spamd daemon with the spamc 
client. After the filtering, it sends the message using the 
'sendmail' (postfix's sendmail) program.

So when I'm getting a large amount of messages there is approx. 15-20 
spamc/spamd running. I want to limit this to ~5. How can I do this. The 
spam user's passwd entry looks like this:

spam:x:2528:2528:spamd:/no/where:/no/shell

It has no shell, so I can not use the ulimit function in bash. But what 
else could I do?

Thanks a lot!

Daniel
