I can attest to what Eric is saying... I use a QMT to front-end for several exchange servers.

In DNS, the only MX records point to MX servers (mail.it4soho.com & mail2.it4soho.com). Note that the latter (mail2) is actually the same "store & forward" config as what you're trying to accomplish!

So, you setup DNS to have an MX record for your QMT server .... and ONLY your QMT server. Then, in your QMT server, you make an entry in the control/smtproutes file that looks like this:
   mydomain.com:lotus.mydomain.com

where lotus.mydomain.com is the IP address of your Domino server.

NOTE: It is NOT necessary for your outbound e-mails to go through your QMT (although you can force that). However, if you specify SPF (in your DNS), you'll need to make an entry for your domino server as well as your mx entries... for example
   mydomain.com.   TXT   "v=spf1 a mx lotus.mydomain.com -all"

I hope this helps... SOMEONE!

I don't think you'll like your idea if you implement it. Many spammers don't
follow the rules, and use the higher priority mail server to send spam to.
Using QMT as a front end for LD is ok, just don't create an MX entry for LD.

What do you mena with do not add them to the machine otherwise?

My idea is to have two mx

10 qmail server
20 lotus domino server

when server lotus domino is not available all the email will stay at
qmail server, when the lotus domino is available all the email from
qmail will go to lotus domino.That's what i want to do.

I want to stop spam at smtp level using spamdyke and graylisting too.

first Qmail then will send clean emails to Lotus Domino

It's possible to do that?


Yes it is. Just set the domains up in rcpthosts - do not add them to the
machine otherwise.
Look on the wiki for instructions on the caching backup server. That's what
you'll be setting up.
