spamassassin 2.53 & MailScanner

[Steve Freegard]

I've got SA running the RBL checks (with Razor2 & DCC) - but I found that SA
2.53 doesn't include the Infinite-Monkeys open-proxy RBL, so I have
MailScanner doing this RBL check instead - which has already picked up a bit
of spam that SA hasn't with no false-positives so far.

As an aside, is Pyzor any good? - I notice SA scores higher for Pyzor
listings than Razor2, and wondered whether it was worth installing as I
already have Razor2??

Kind regards,
Steve
