I hope no one is tempted to run that for mailservers which they don't
admin; both dwmw2 and myself setup filters on our mailman lists in the
MTA to prevent bounces to the list posting address at SMTP time.
This means recipient verification using <> as the sender fails.
Of course, we can work around the problem ourselves by setting the
option since we admin our domain.
My point is that recipient verification should only be used for domains
under the same administrative control.
