Hi,

I have to parse sendmail maillog to get the DKIM-Signature headers. So I decided to extend the Perl Module: Parse::Syslog::Mail;

to handle DKIM-Signature headers {we use dkim for encyption).

This module includes:

if (exists $mail{ruleset} and exists $mail{arg1}) {
    $mail{ruleset} eq 'check_mail'  and $mail{from}  = $mail{arg1};
    $mail{ruleset} eq 'check_rcpt'  and $mail{to}    = $mail{arg1};
    $mail{ruleset} eq 'check_relay' and $mail{relay} = $mail{arg1};

I am trying to find out whether a ruleset exists for the DKIM-Signature header, and if not, where I go to find the other rulesets and add one.

Below is what the DKIM-Signature header looks like, I need to get the domain "d=" and selector "s=" from this DKIM-Signature header:

Nov 27 15:08:23 sender03 sendmail[1016]: lARN8MsF001016: Milter
insert (1): header: DKIM-Signature:  v=1; a=rsa-sha256;
c=simple/simple;\n\td=yahoo.com; s=1319567451;

Any help would be much appreciated!
