Hello,

This can be done with a milter filter, you can google to find the best way to do this. One way is using python :

I suggest to test this on a test server first.


If all your mail comes from the Web-UI it can also be done with a Zimlet viewtopic.php?t=44681

There is also this wiki article, did you look at that? I did not try it, but it seems like an easy solution:

Probably you can also do this with postfix, google `postfix add custom header` and then apply it to Zimbra.
