The answer to your question is yes, if set up correctly at a DNS level, all
you have to do is have it running, it will take all mail that the primary
would normally receive, and within about 5 minutes of the Primary coming
back on line, it will dump the mail across. The page you refered to is
actually instructions for a mailfilter called SCMS, which is an excellent
add-on for this program (again it's freeware), it is a very cmplete
anti-spam/relay set of plugins.
If for some reason you've got something against freeware, try MailSite.
It's based on the same code, and just as solid but with a greater array of
Hope this answers your questions.

Subject: switchover SMTP with Exchange and IMS
I've looked everywhere and couldn't find a lot of information about
switchover SMTP under NT 4.
Here's what I'd like to do :
I have one machine with MS-Exchange as SMTP-POP3 server.
I want to shut it down.
On another machine, I'd like to install another SMTP server (Exchange
or, better, a freeware like EMWAC's IMS) that would get incoming mail while
the other is down.
(this sounds possible, with a correct DNS MX setting)
Has anybody already experienced it ? Do you have other ideas ?
