I found this in the book Microsoft Exchange Server 2003 24seven by Jim McBee(with Barry Gerber)on page 794:

I'd much rather lose a frontend OWA/SMTP box than a mailbox server; at least I'd keep internal messaging functional. Either way, having a proxy server between Exchange and the internet is a good idea if you can swing it. As far as I know, you can't run E2K frontend to E2K3 backend. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mulnick, Al Sent: Friday, January 28, 2005 8:29 AM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] OT:exchange frontend IMHO, same risk is taken in regards to being hacked. As for operational availability risk, a FE server serves two purposes in my opinion: it allows you to hide the mail store for the user thereby allowing higher scalability and it also buffers the mail flow if deployed for the SMTP as well. That allows you some room to work if the mail gets backed up for some reason yet the mailboxes are still functional internally. Outside of that, it wouldn't be much of a difference in most cases.
