Re: [exim] "sender verify defer" although no "verify sender"

yes, for sure. But most simple clients don't check for errors. They just
send an email to a recipient, that really exists. But if the mailserver
refuses their email because of a wrong sender address, neither they
receive an error message nor the recipient receives the email, although
there's no reason why the email is not received.

We do, but disabled sender verify is nothing that brings us on black
lists. And to be honest: I don't know any provider, that blocks emails
because of a not valid sender address.

But anyway: My problem is, that the sender verify seems to be done
although exim isn't explicitly told to do it. So how can I really
disable it, or what is causing exim to do the check although it's not in
the ACL?
