It's not that a bad idea, honestly, just don't use the default 5
theshold, but a higher one.

I also have postfix hand mail to spamassassin before it's delivered to
cyrus. However, I found it even better to permban several (useless for
me) TLDs at the firewall level (*.es *.kr *.cn *.tw and several
southamerican countries) I'm aware you can't do that on a server like
FreeBSD's, but found it extremely useful on my own one. I, personally,
have never recieved a legit mail from any of those countries.
The spam problem is a touchy one, but I'm sure some meassures are taken
at the server level for the mailing lists. I once heard a SPAM attempt
hits the FreeBSD mail servers once a second.
Cheers,
