Re: SMTP service and routing groups
SMTP is the transport used by Exchange 200x servers to transfer mail - even
between 2 Exchange servers in the same Routing Group. You shouldn't remove
SMTP svc from Exchange servers - except on Front-End servers where you don't
want to use SMTP (the FE will only be used for HTTP (OWA), IMAP4 or POP3).

To route mail to/from the Internet you can setup a smarthost in your DMZ.
This can be a non-Windows box running SMTP (like postifx, sendmail, et al),
or a Windows box running IIS SMTPsvc (that's not a member of the domain).
Set up a SMTP Connector to deliver to this smarthost. Alternatively, you can
also use your ISP's smtp server - contact them for details. Another
alternative is to use a service provider like Postini that also does
anti-spam/anti-virus on smtp mail.
The MX record in external/public DNS points to this smarthost as well.
This allows your internal Exchange server to only communicate with a single,
trusted smtp server (either on your DMZ or at your ISP) to send/receive
internet mail.

that sort of answers the question. But what I am really looking for is
any white paper that talks about best practices fro SMTP service on a
FrontEnd or BackEnd. I know that you need smtp to talk between servers,
and if you stop it, well, you are SOL.
