[exim] Failure to transfer data from subprocess

Trying to lock down permissions on the email system which doesn't use
real unix usrrs. So I tried setting the permission on Exim to 750 so
that only processed in the "mail" group can run it and I put spamd,
clamav, and everything else I can think of in the mail group, yet I get
this error message:

"Failure to transfer data from subprocess"

Any ideas?
