For "Sender: " it means it is from a mailer deamon, but if it
is '<>' in all three of those then something is wrong -- from
my reading of the Exim manual, headers_sender_verify_errmsg
in particular. If that is not true (and I have just failed
to find the string "<>" in RFCs 822, 2076) then what is the
purpose of headers_sender_verify_errmsg?
I'm not sure how the try vs non-try versions of sender_verify
interact with this hehaviour.
