I would like to automatically reject any mail that doesn't
- Contain a subject line OR has a certain subject line (like "FW:")
- Contain any text in the body
I assume that a postmaster filter would be the first step.
I see I can set the header to XOTRS-ignore but I have tested with this and it does not send a notification and it also seems to deal with any part of the subject containing the reject words. i.e. if I am rejecting the word "FIVE" and the customer just has "FIVE" in the subject line then this should be rejected, BUT if they have "FIVE ANY OTHER WORDS" then this is valid and should not be rejected.
Could you please suggest a good way to go about this?
