[Exim] Exim Corrupting mailboxes - my fault I guess

Hi,
I have installed Exim 3.12 on a 5.04 sendmail replacement. Everything
seems to be working fine, but exim does not seem to be putting in the
^A^A^A^A mail separators. The separators between 2 emails is two line feeds
(0x0a).

Any ideas?

Cheers Scott
