Yes perhaps using blacklists, but this is not the best method to fight spam, did you already implement other anti-spam measures available on SME Server?

Using Geoip works fine for me!

This panel gives you access from the server-manager to several different levels of white and blacklists including qpsmtpd badhelo and qmail badmailfrom.

yes, and it generally works great but right now I am getting about 3500 fake bounce and other spams from russia per hour and I need to get qmail to drop them so spamassassin doesn't have to scan them.
-
Is this stuff really from russian IPs or is it just a spoofed from:address <spoofed_user@spoofed_domain.ru> ?
-
I'm not the one receiving these. I'll see if that user will forward several to me.

It looks like about 70% are Russia, 20% US and the rest scattered around the globe.
-
Did you check out TearGas' suggestion. It should at least get the russian ones and if you receive no legit mail from russia shouldn't cause a problem.
I am not sure if you can block all .ru domains with the qmail blacklist. (at least I can't find the format you would need to use.)

Yes, I installed that. It seems to be working very well.
in the last minute it has been

So, I got rid of a few of those country codes also. This is for a school and the only people they need to communicate with "per the principle" are their parents board and other local supplies and other schools. All US in other words.
