How to Increase Exim4 Logging Information

Last Updated on June 16, 2020 EDT by Jordan

This is pretty simple to do, the syntax is as follows.

log_selector = +address_rewrite +all_parents +arguments +connection_reject +delay_delivery +delivery_size +dnslist_defer +incoming_interface +incoming_port +lost_incoming_connection +queue_run +received_sender +received_recipients +retry_defer +sender_on_delivery +size_reject +skip_delivery +smtp_confirmation +smtp_connection +smtp_protocol_error +smtp_syntax_error +subject +tls_cipher +tls_peerdn

However, depending on your OS, you will need to add this line to /etc/exim.conf or if you’re running cPanel you can follow these instructions.
