What rates of spam detection are you getting with surbl ? And what methods do you use to complement it. I would like to run some RFC checks but some of them seem to stringent.... I.E - Reverse PTR checks, etc
RFC checks, reverse DNS lookups, etc are nearly worthless since so many mailers are not configured correctly.
I must admit that I'm finding it difficult to make any sense of this statement at all.
"Many mail servers are broken, so checking for brokenness is not useful?"
I tend to view this another way:
"If you do not accept mail from broken mail servers, maybe the idiots responsible for their being broken will fix the damn things."
If 80% of the world's nominally legitimate mail servers are not RFC compliant, should you only accept mail from the 20%. I tend to doubt it.
