Nope. There are burned IPs that had been previously been used by spammers and
there are even complete ASes, owned by hosters that just don't seem to be
able / willing to get control over outbound abuse from their networks.
Regarding this it *does* make sense to check an IPs reputation *before* you
run a mail service using that IP.

Besides that: I'd like to keep it classy. I don't see any reason to offend
anyone for a discussion over IP.
