Exchange 2003: Branding outgoing e-mails with a different domain?
Posted on 2005-05-04
A client of ours owns two domain names. For future reference - and simplicity - let's call them 'domain1.com' and 'domain2.com'.
The MX record for domain1.com points to a Windows Server 2003 (Small Business Edition) machine running Exchange 2003.
The MX record for domain2.com points to a POP server hosted by a local ISP. We have set up a POP3 connector on their exchange server to grab the e-mail from that account and dump it into their exchange mailbox. So far so good. But, quite naturally, any e-mail they send comes out as 'firstname.lastname@example.org'. For legal reasons, our clients are insisting that the e-mails need to be sent from 'email@example.com'.
To make matters more interesting, the user who needs this particular functionality is a mobile user, roaming the country, laptop in hand, err, lap... sort of thing. This means we can't just set their Outlook client up to just send and recieve from the local ISP server.
So, my question is this: Is there a simple way to get Exchange server to brand outgoing e-mails from a single 'domain1.com' user as 'firstname.lastname@example.org'? Can this be done securely? I have tried just changing the 'from:' field, but e-mails just get rejected with a permissions error. They (hopefully...) will be accessing the server via VPN. So I could assign them a static IP address if that's necessary.
If Exchange can't do it natively, I'd wouldn't mind the name of any software under A$500 or so that could also help. Over that price and it'd be cheaper to set up an IMAP server on a Linux box.
Any help would be grealy appreciated.
