Postfix and protective markings...
I have a running Postfix / Amavis-NEW / ClamAV mail gateway. I am trying to implement protective markings for the organisation.
I have a few questions on how to do this:
1. How do i only allow this header check to be applied from a certain host. This mailserver is both a incoming and outgoing MTA...
2. I suck at regular expressions so can anyone help making one that checks one of three strings in the subject line (personal, unclassified, classified).
3. With the REJECT option within header checks can you specify a custom return message.
4. This needs to be applied to all mail, with one or two exceptions. Some hosts might not be able to have protective markings so can they be excempt from the header_checks.
I have added the line from the header_checks readme to point to /etc/postfix/header_checks.pcre and the main part is what need to go in that file to do the job.
I would like to thank everyone in advance for your help...
