Hello.
After some investigations, it seems that the relevants configuration
instructions
are in /etc/exim4/conf.d/acl/30_exim4-config_check_rcpt :
# Deny unless the sender address can be verified.
#
# This is disabled by default so that DNSless systems don't break. If
# your system can do DNS lookups without delay or cost, you might want
# to enable this feature.
.ifdef CHECK_RCPT_VERIFY_SENDER
deny
message = Sender verification failed
!acl = acl_whitelist_local_deny
!verify = sender
.endif
But where or how is set the variable CHECK_RCPT_VERIFY_SENDER
and what should I change here to get what I want ?
Thanks once again.
