Hi, There are a number of postings pertaining to the insertion of an X-EnvelopeTo header on all incoming mails, but there doesn't seem to be a terribly useful solution to the problem as far as I can see. The situation is that the envelope must be added to all mail so as to include the original "To" address in the envelope after a mail is forwarded in order to ensure compatibility with all of our existing mail users. I have played around a little with some ideas, but to no avail. Could someone please point me in the right direction. Many thanks in advance, Tristan Graham.
