[brlug-general] spam filters

[Shannon Roddy]

Hi Folks,

I've got a couple of domains that receive email directly.  I do not
currently have any spam filters configured on them.  Things have
stayed below the radar... till now.

Does anyone know of :

a) a cheap or free service I can point my MX record to and have them
filter mail for me?
b) a fairly easy to use (free) set of scripts to "pre-train" something
like spamassassin?  I really don't want to learn the nitty gritty of
configuring it myself.

(A or B are preferable) or

c) a quick easy cheat sheet on configuring spamassassin and clamav on
Ubuntu (6.06 LTS)?

I really am time challenged lately, so I would prefer to point the MX
record elsewhere and let someone else filter the mail for me.

Thanks,
Shannon
