Hi DU Admins
The original question is below. I think I've solved this myself.
Removing FEATURE(nocanonify) from the null clients' config fixes
the problem. However this canonifies all addresses - both
sender and recipient - with the server's address. So far this
isn't causing any problems.
I was looking for a solution which would just add the domain to
sender addresses so if anyone knows a way to do this I'd still
be interested in hearing about it.
Original Question:

Thanks
