Logging received from timestamp in postfix

  • 772

For incoming emails to a postfix server, i would like to record the timestamp in the "Receive: from" header.

For example, from an email containing:

Received: from mailserver01 ([192.168.0.25]) by mailserver01.domain.intra with Microsoft SMTPSVC(6.5);
 Mon, 16 Jul 2012 17:09:36 +0200

I would like to extract:

Mon, 16 Jul 2012 17:09:36 +0200

What i would like to know is how to configure postfix to log that information (just the timezone or the whole "Received: from" header). I can handle the parsing to extract the information once i have that line logged.

  1. You can pass it to cut 

    echo "Received: from mailserver01 ([192.168.0.25]) by mailserver01.domain.intra with Microsoft SMTPSVC(6.5);      Mon, 16 Jul 2012 17:09:36 +0200" | cut -d ";" -f 2

    or if you place email content in bash variable:

    cat $email | grep "Received:" | cut -d ";" -f 2

    I'm not aware of any config option to customize the log format. Have you tried running postconf to see if there's any option that deals with the log format?

    Anyway, a similar question has been asked before, and it seems that it's not possible
