Variable de IP del servidor enceived_header_text en la configuración de exim

Question

Me gustaría cambiar el texto_encabezado_recibido en la configuración de exim y necesito usar la IP del servidor en él.

¿Existe alguna variable que pueda usar para obtener la IP del servidor?

Pensé en cambiar:

received_header_text = Received: ${if def:sender_rcvhost {from $sender_rcvhost\n\t}{${if def:sender_ident {from ${quote_local_part:$sender_ident} }}${if def:sender_helo_name {(helo=$sender_helo_name)\n\t}}}}by $primary_hostname ${if def:received_protocol {with $received_protocol}} ${if def:tls_cipher {($tls_cipher)\n\t}}(Exim $version_number)\n\t${if def:sender_address {(envelope-from <$sender_address>)\n\t}}id $message_exim_id${if def:received_for {\n\tfor $received_for}}

a:

received_header_text = ${if def:authenticated_id {Received: from $primary_hostname ([188.40.153.39] helo=[188.40.153.39]) by $primary_hostname with ESMTP\n\t(Exim $version_number)\n\t${if def:sender_address {(envelope-from <$sender_address>)\n\t}}id $message_exim_id${if def:received_for {\n\tfor $received_for}}\n\t}}Received: ${if def:sender_rcvhost {from $sender_rcvhost\n\t}{${if def:sender_ident {from ${quote_local_part:$sender_ident} }}${if def:sender_helo_name {(helo=$sender_helo_name)\n\t}}}}by $primary_hostname ${if def:received_protocol {with $received_protocol}} ${if def:tls_cipher {($tls_cipher)\n\t}}(Exim $version_number)\n\t${if def:sender_address {(envelope-from <$sender_address>)\n\t}}id $message_exim_id${if def:received_for {\n\tfor $received_for}}
