That isn't the odd DNS lookup bug in 2.04 biting, is it? Once you enable
sender_host_reject, exim does a reverse lookup on the incoming IP, then a
forward lookup on the name it gets. If they don't match, it bounces the host
or the recipients.
2.04 had a bug which caused a core dump (and a drop of the connection) if
the forward lookup above failed. There was a patch circulated - and 2.05
fixes it, too.
