Hi list, I'm looking for an easy way to add a static prefix "[*EXT*]" to all incoming emails, as long as the subject does not already contains this string. OpenSMTPD is running as a filtering MX running senderscore filter. default action is relay to another host.
Can OpenSMTPD modify the header conditionally ? If so, should I add a filter to the existing "listen" line or should I add a new "listen" line with a dedicated filter and chaining listen->action relay to local listen->action relay to external ?
