Here, I deny if the sending address doesn't match the authenticated ID
before denying the sender from a barred sender list.

acl_smtp_mail = acl_check_mail
...
acl_check_mail
...
deny message = Your sending address and authenticating ID must match.
authenticated = *
condition = ${if eq{$authenticated_id}{$sender_address}{no}{yes}}
log_message = Sender address ($sender_address) does not match the \
authenticated ID ($authenticated_id).
deny message = Your sending address is barred from sending messages.
authenticated = *
senders = /usr/local/etc/exim/senders_barred
