    Hello,

    The sender's authentication type in delivery event details show dovecot_login , forwarder and localdelivery , what does mean each one of them ? and is there other type?

    Same thing in the Transport there is dovecot_virtual_delivery , dkim_remote_smtp and dovecot_virtual_delivery_no_batch

    I would like to know what each type mean and is there other types ?



    Regards
    Qasem

    Hello @Qasem_AM


    These are all transports that are setup in the exim configuration.
    The thread here dovecot_virtual_delivery explains a bit more what virtual_delivery ones the dkim_remote_smtp is the name of the transport that does remote host lookups:

    Code:
    dkim_remote_smtp:
      driver = smtp
      interface = <; ${if > {${extract{size}{${stat:/etc/mailips}}}}{0}{${lookup{${lc:${perl{get_message_sender_domain}}}}lsearch{/etc/mailips}{$value}{${lookup{${lc:$original_domain}}lsearch{/etc/mailips}{$value}{${lookup{${perl{get_sender_from_uid}}}lsearch*{/etc/mailips}{$value}{}}}}}}}}
      helo_data = ${if > {${extract{size}{${stat:/etc/mailhelo}}}}{0}{${lookup{${lc:${perl{get_message_sender_domain}}}}lsearch{/etc/mailhelo}{$value}{${lookup{${lc:$original_domain}}lsearch{/etc/mailhelo}{$value}{${lookup{${perl{get_sender_from_uid}}}lsearch*{/etc/mailhelo}{$value}{$primary_hostname}}}}}}}{$primary_hostname}}
      dkim_domain = ${lc::${if eq {${perl{get_message_sender_domain}}}{-system-}{$sender_address_domain}{${perl{get_message_sender_domain}}}}}
      dkim_selector = default
      dkim_private_key = "/var/cpanel/domain_keys/private/${dkim_domain}"
      dkim_canon = relaxed
      hosts_try_chunking = 198.51.100.1
    For the other two this explains it well also:

    Code:
      #
      # If the delivery address, original address (forwarded),
      # or address with subaddress is shown on the To: or Cc:
      # lines or the message has the List-Id: or Precedence:
      # header we allow the message to be batched to
      # dovecot LMTP via transport dovecot_virtual_delivery
      #
      # If it does match match the above we do not allow the message
      # to be batched in order to ensure that the Envelope-To: header
      # does not contain a user that was Bcc:ed so savvy recipients
      # cannot see that another email was Bcc:ed in the header
      # via transport dovecot_virtual_delivery_no_batch
      #
      # Note: match_address would be nice here but the second string
      # is not expanded for security reasons
      #
