We have a user that subscribes to an mailing list on the internet. He uses a server side filter to forward that mailing list traffic to an internal distribution list.

In 6.0.4 it was doing more of a redirect where people who are on the internal dl would see the email as coming from the original external senders.

Now in 6.0.5 it's doing more of a forward where people on the internal dl see the emails as coming from the person who has this filter set up.

It looks like zimbra fixed a bug to make "Forward To" literally forward to. But we liked the other behavior. Is there a way to have server side filters re-direct emails in 6.0.5?

Or is there another way that we should set this up? Preferably a way that does not burn a user license just for this mailing list re distribution.
