I think you misunderstand what greylisting is. Your first message to an
MTA that uses greylisting will be delayed. The delay is a function of
your MTA's retry process. Once that first message is allowed through
subsequent messages are auto-whitelisted. Most implementations expire
auto-whitelisted sites so periodically one of your messages may be
delayed again.
I think one problem arises if a different server retries the e-mail. Red
Hat's greylisting software will see that the email comes from a
different IP address, and delay it again with another 451.
Worse, once the e-mail has got through from one server, the others won't
retry. The greylisting software will spot that the other servers tried
to send an e-mail and didn't continue until the e-mail was successfully
delivered, and mark the servers as "dodgy".
Antonio's best bet is to e-mail the mailing list owner (see the URL in
the standard list signature), and see if Red Hat can whitelist his ISP.
Obviously, I can make no guarantees that they *will*.
