How to configure Sendmail to record the email subject in logs

[hdc]

Hi All,

The version of FreeBSD is

FreeBSD 12.0-RELEASE-p3 FreeBSD 12.0-RELEASE-p3 GENERIC  amd64

So far I can see log from maillog like this:

Aug 29 17:08:49 foo sendmail[30651]: x7TF8mLL030651: to=bar, ctladdr=foo (80/80), delay=00:00:01, xdelay=00:00:00, mailer=relay, pri=170288, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (x7TF8nTs030652 Message accepted for delivery)
Aug 29 17:08:49 foo sm-mta[30654]: x7TF8nTs030652: to=bar, delay=00:00:00, xdelay=00:00:00, mailer=esmtp, pri=170532, relay=bar.com, dsn=2.0.0, stat=Sent (<bar> [InternalId=174410031956017, Hostname=bar.com] Queued mail for delivery)

How can I add email subject into this log?

Adding this to your .mc file and regenerating .cf should do it:

HSubject: $>+LogSubject

LOCAL_RULESETS
SLogSubject
R$*    $: $(log Subject: $1 $) $1

I have added them to my .mc file and make the .cf file but nothing changed.

here is my mc file

HSubject: $>+LogSubject

LOCAL_RULESETS
SLogSubject
R$*    $: $(log Subject: $1 $) $1

Run make install and make restart in /etc/mail. And you may want to review your files, the version string at the top indicates 11.0-RELEASE (releng/11.0), not 12.0-RELEASE (releng/12.0).

Looking at my .mc file I see I actually have:

LOCAL_RULESETS
Klog syslog
HSubject: $>+LogSubject
SLogSubject
R$*     $: $(log Subject: $1 $) $1

Note: There is a TAB character between R$* and $: in the last line which is necessary.

This yields in the mail log file:

Sep 12 16:13:43 shadow sm-mta[56075]: x8C6DhU6056075: Subject:Testing
