I have setup zimbra for a NGO (non-profit, non governement organization).

They didnt have a static ip, they have a hosted website where they download all their email from.

The problem i am having is that some of their emails are being bonuce back, because they are using a no-ip.com to give them an easy login to zimbra web interface from their browser.. example helphands.no-ip.org.

Is it possible to route all their email back to through the hosted website email ??

I hope i am making sense.
