[EXIM] How to reject one host from an accepted net?

Hello again

Is this a bug? v2.02 on Digital-Unix.

If I have

sender_net_accept_relay = "1.2.0.0/16"
sender_net_reject_except= "1.2.0.0/16"

How can I then reject connections from just one host as
sender_net_reject = 1.2.3.4/32
doesn't seem to work if I use the test mode
exim -bh 1.2.3.4

(using real nets and hosts for the tests, of course)

I want to be able to block one or more hosts from even connecting if
they become a problem for whatever reason, I could build in tcp_wrapper
support but then lose the central logging???

Thanks
Neil
