Dear colleagues,
kindly looking for your assistence in the following matter.
To cut off the spamers, I intended to use pcre:table.
WOuldn't it be easier to use an RBL instead?

Nope. Postfix hands down the IP and it hands down the hostname IF the
hostname resolves back and forth.
Yes, I know.

the debuging rule is working instead the of first one.
Why does the postfix ignore the first rule?
I'd think the regexp is wrong
Why this regexp is "wrong" for postfix, but isn't wrong for postmap?
