[Exim] Sender verify did not complete

I had exim working on OSX Server 10.2.1 and after upgrading to 10.2.2 it
seems to have broken.
Incoming mail to shows the following entry in the mainlog:

2002-11-17 19:58:27 H=(mta7.pltn13.pbi.net) [64.164.98.8]
F=<me@???> temporarily rejected RCPT <user@???>: Sender
verify did not complete

I am pretty new at this and any help will be appreciated.
