Morning all,

I have just come across something that strikes me as a little peculiar.  I
don't know if it's a FreeBSD peculiarity, or an Exim oddity.

My MTA is exim 4.20.  I had left the $primary_hostname unset in my config
file, expecting exim to take the return value from uname(3), which is the

Explicitly setting $primary_hostname in the exim config fixes the problem -
my posts now get through to the list again.

Just wondered if anyone could shed any light?
