mx2? You're not advocating a secondary MX machine, are you?

Although "best practice" when the specs were originated, a secondary MX
these days is no longer appropriate for a small net presence.
Dual-primary is fine, but secondaries are no longer a good idea.

*If* the secondary has an equivalent anti-malware setup (which means at
the very least that it always has the up-to-date list of valid users)
then it's possibly of value - otherwise it just acts as a spam-soak, and
when it re-delivers to the primary, you've lost all the originating-IP
address details used by RBLs to block the message (as opposed to
labelling it as spam by content inspection)

Once you've one through the pain of figuring out qmail's config
idiosyncracies, and patched it with the features you want, I can see
absolutely no reason to move away from it :-) I'd never recommend
installing qmail over anything else, but once it's in and running it's
still stable as hell and very fast. No need to change.
