We just have in Exim's configure file

never_users = root
trusted_users = prayer

prayer has it's own group, i.e. not shared with Exim. Dovecot is on a
completely different server.

We just have
sendmail_path = (path to exim binary)

Us too of course!
Do you get an error in Prayer's session_log?

That *is* odd! Maybe something that happens in BSD but not Linux? (We
run Prayer and Exim on Ubuntu 8.04 and SuSE Enterprise 9)

What are your log settings in Prayer and Exim?
