Guys, I am having some issues with particular servers sending emails to my server. Those other email server administrators just tell their users (who I found out from) that it is my email server problem and they do not want to help. I can send to them no problem, but not receive from them and zero log entires of their server contacting mine at all. I saw an entry that enabled verbose logging in my exim.conf: log_selector = +address_rewrite +all_parents +arguments +connection_reject +delay_delivery +delivery_size +dnslist_defer +incomi ng_interface +incoming_port +lost_incoming_connection +queue_run +received_sender +received_recipients +retry_defer +sender_on_d elivery +size_reject +skip_delivery +smtp_confirmation +smtp_connection +smtp_protocol_error +smtp_syntax_error +subject +tls_ci pher1 +tls_peerdn but my logs look no more verbose than before. Any help? any other ideas to track the incoming connection, or determine if there actually is one at all (i.e. maybe it is some failure before they even try to connect)? Thx! Helmut
