Logging mail subject headers in Postfix

timjames · 07-29-2003, 06:16 AM

Hi,

I want to log the email subject line in the Postfix maillog file.

I have tried using 'always_bcc' to redirect email to a fake user which redirects the email header to the mail log file, using sed command in aliases. Unfortunately this is not working, as it appears Postfix is not sending any mails to bcc.

Any one any ideas on this. It seems a pretty common thing to request, but I haven't had much luck finding any answers on this one.

Thanks,
Tim.

Here are the steps:
edit the /etc/postfix/main.cf files add the following line to the header_checks section:

header_checks = pcre:/etc/postfix/header_checks

Edit the /etc/postfix/header_checks file and add the following:
/^Subject:/ WARN

check out /etc/postfix/header_checks file for more info.
