Hello Mark,

thank you for your reply.
I have a "Local Postmaster" setting set.
I also have set "Notices From" and "Notices To".

The messages without "From: " header are *notices to senders* who's mail
has been rejected for some reason (forbidden attachment file type).

Is there something else I could check?

Thank you.
