The problem with qmail is that you need either a big patchset or a once patched setup and reuse that. Plus qmail really has some not-so-nice bugs.
We use a qmail-ldap [1] setup (qmail + single patchset) for years with a similar workload and it works quite fine. However as you already said, there are some annoyances with qmail which are not that nice... one of the biggest drawbacks is that it's not actively maintained anymore and you have to either use alternative components if you need a new specific feature (like smtp daemon with support for filtering, greylisting or whatever) or manually adjust patches because usually the different patches are not interoperable. However, many annoyances are already addressed in the qmail-ldap patchset and because qmail is modular it's not a big deal to replace parts which you don't like.
What you have to consider when using qmail is that the disk i/o performance is far more critical than for other MTA's - fast disks are a must, at least for the queue partition.
