[exim] No Reverse DNS

I have this to block connections with no reverse DNS:

# : no reverse dns
#defer !verify     = reverse_host_lookup
#      message     = Reverse DNS lookup failed for host $sender_host_address

I had to disable it though since it blocked some of my own users.

Is there a way to get it to ignore connections listed here?

net-lsearch;/etc/virtual/pophosts : /etc/virtual/relay_ips : 127.0.0.1

Anyway to ignore connections on port 587? Anyway to ignore
authenticated SMTP users?
