[Exim] require verify = header_sender

Hi

I have a customer who is trying to send mail from a perl script on the
web machine through our smtp server. It keeps getting rejected (reject
example below -- addresses modified from actual for this example), and
after some tests, it doesn't seem to matter what he sets for the
sender. His script makes the From: be whatever the user typed in and
sets the Sender to be some valid email address of his (and all mail
goes to his mailbox -- a feedback form of such). So with the Sender
set to a valid email I still get the following bounce at the bottom. I
assume that this is the result of the following acl (acl#1)? (or is it
the result of verify = sender in acl #2)

(acl#1)

#!!# ACL that is used after the DATA command
check_message:
require verify = header_sender

(acl#2)

#!!# ACL that is used after the RCPT command
check_recipient:
...
   deny    hosts = ! some.host : \
           *
          !verify = sender

These came from the rewrite script from an older Exim3 config
