How can I use Postfixas a backup for an NT MTA?

[wilson claborn net (Jonathan Wilson)]

Howdy,

My boss wants to use our main /Linux/ server as a backup MTA for our main mailserver, which sadly is running NT.

Our Linux server is RH 6.2, running postfix - very successfully, too. Only problem is I have no idea how to do this in any operating system - In fact I've never really dealt with NT mail.

To clarify things, what we're really needing is a backup for SMTP service. The pop3 users can "just sit on it" if they can't check their mail for a minute, but we can't have our incoming mail lost in cyberspace. I'd be curious to know if backing up pop3 is even possible - I don't quite see how it could be, short of running the whole outfit as a virtual server (which we hope to try someday).

Any ideas, advice and opinions or instructions would be greatly appreciated :-)

TIA,
