It is just nuts.  I use this as workaround, though:
  warn   !acl       = acl_whitelist_local_deny
         message    = Sender verify failed
         !dnslists  = dsn.rfc-ignorant.org/$sender_address_domain
         !hosts     = +no_check_hosts
         !verify    = sender/callout=3m,defer_ok


And then I set some acl_m* variables, and look at them later. If your
friends domain isn't already in dsn.rfc-ignorant.org, report him, and
then you won;t reject his mail. Or you could use an explicit
!domains = my.friends.domain
in that acl part.
