How to Enable Extended Logging

November 27, 2006 / General Discussion

To enable extended logging in Exim to trace nobody’s mails.

Try the following trick.

  1. Edit /etc/exim.conf
  2. On the second line add:

    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 \

    Make sure all that comes on a single line.

  3. Save and exit.
  4. Restart Exim.

A little bit of luck and you should be able to catch the spammer.
