I am surprised, as by docs, it has do exactly that, how did
you set it?

Not really as complicated as it can look...
When you will check recipient in warn (instead of deny), the
deffer will not be final result, but only end of warn section,
thus one can use something as this (from head only, not
tested):
warn
set acl_m_rcptno = 1
verify = recipient
set acl_m_rcptno =
deny
condition = $acl_m_rcptno
set acl_m_rcptno =
In warn it first sets ACL variable as mark of failed RCPT
verify, then do verify, it is success, then clear variable and
deny will not happen, but when verify is not success, the
warn will end at this point and variable will not be cleared,
thus deny will happen in nect section.
When verify triggers defer, the warn will be intercepted, and
ACL will continue with deny... In deny is variable cleared too,
to not leak mark to next recipient of the same message, if
any...
Anyway, i would prefer to have option for retry to one can
set short (eg. 1-2 hrs) threshold for temporary DNS errors,
but i see no one.
