I did have a retry file in the exim.in/db directory - which was
causing the bouncing. However, I think I know how this got there.
Cron on FreeBSD runs sendmail (well, exim) with the -odi flag, which
causes a second exim process to attempt delivery - even with the
queue_only option switched on. Turning off this flag seems to have
gone part way to fixing this... but it's still not entirely happy.
It'd be nice if exim had a queue_only_always flag which would make it
queue every time, and not permit anything else.
