Exchange can use SMTP, but only as a simple delivery/receiving of mail.
Hence the term Simple Mail Transfer Protocol. It can not be setup custom
like Qmail by any means.
In the Exchange's routing, you may be able to configure the domain mask to
change on SMTP outbound. Which means you may could route to different
Qmail servers. But it is no where near as versitile as Qmail.
