Some composite DNSBLs e.g. sorbs (
www.sorbs.net) return multiple A records
where an IP is guilty of multiple offences. This is different from
the bitmask response used by RBL+, blitzed and others.
Can anyone help me clarify exim's behaviour in the multi-A case ?
I assume that:
dnslists = bl.example.org=xxx
is true if any of the A records returned equals xxx. But what about:
dnslists = bl.example.org!=xxx
Is this true only if *no* A record equals xxx ?? Or is it true as long as
there exists some A record not equal to xxx" ??
I'm not sure this is clear from the spec or newstuff file. Perhaps I'm
missing something.
