I'm having an increased amount of junk getting through due to it coming from Hotmail and Yahoo's servers which makes any type of pre-filter stuff like RBL's, Greylisting, Sender Verification useless which leaves me to rely on Spamassassin. I cannot block hotmail and Yahoo (although I would like to personally) as our users receive valid email from them.

I have emailed there abuse but it seems more like a blackhole.

I was advised by the Postfix mailing lists to see if anyone here can help me out.

Important Note: I am planning on upgrading the Spam Gateway we are operating to utilise Maia Mailguard and therefore allow easier training of the spam filter which will hopefully help in fixing the problem anyway but was wondering if anyone ha some tips on how to kill this junk.

I have added higher scores such as "score DRUGS_ERECTILE 7.31" but that doesn't help with all the spam.

Examples are below.
