Hi, What would be the best way to identify email which is forwarded to external addresses by .forward, procmail or sieve rules?
We have control over the mail gateways which handle all incoming-outgoing traffic, but no real access to the internal servers where the forward rules may be entered. Add a specific header (e.g. X-Delivered-To) to the incoming email (it could be deleted, but let's ignore the possibility) and check it in the ougoing ones? What are the possibilities for false positives and negatives? Checking the Received lines looks harder and not better approach.
