Its not a sender-verify like that. I THINK all it does is make sure
the sending email adresses domain has an mx record. I did not add
this to my exim config its just been there for years.

# Deny unless sender address can be verified:
# This statement requires the sender address to be verified before any
# subsequent ACL statement can be used. If verification fails, the incoming
# recipient address is refused. Verification consists of trying to route the
# address, to see if a bounce message could be delivered to it. In the case of
# remote addresses, basic verification checks only the domain.
require verify = sender

Does anyone else have this in the exim.conf? This 4.6 Exim.
