We have had various troubles with sender verify, however I am not sure that
any of my users would care to receive messages from a domain without some
basic means of receiving a reply. At this point, I am not considering
whether the mx record is valid, but I would like to block domains without
one. The RBLs are strugling to keep up with all the random "innovative"
domains, this seems to be a good tool in the anti-spam arsenal.
