Hi Craig,

Thanks for the help.

> I'd like to know what's in /usr/local/etc/rc.d/mimedefang.sh...

OK...  The main thing I have changed in here is MX_USER. Initially the 
script had it as @DEFANGUSER@  That didn't work, it complained there was no 
such user (my mimedefang user is defang). So I changed that to @DEFANG at . It 
still complained there was no such user. The only way I found to make it 
happy was  to remove the @'s and change it to just defang. I'll go now and 
make these changes you suggest (including changing the user here to 
mailnull

# requires attention.)

# The next setting is an absolute limit on slave activation.  The 
multiplexor
# will NEVER activate a slave within MX_MIN_SLAVE_DELAY seconds of another.
