Hey Michael, Just to add a small bit, try the same question on the lists of the other "contenders" you listed. See if you get a response from the 2 leading developers within a few hours like you did here.

The timeline's pretty flexible... What I have in place is working, and I've got the hardware and rack space to build the new system without disrupting the existing. The only "Pressure" to get it done is that which I place on myself. I'd like to get it done so I can move on to the next one. :-) > Vpopmail in QMT uses a Mysql DB.

I've done this before, also, and have looked at possibly implementing this is my setup, and may in fact include it in my plans, to some extent. > I'm going to start a video series on the magazine this > coming week on how to build a cluster that replicates all the data > between all the machines (database and mail store), so you could list > all of your mail servers as MX records (or even a single MX record with > multiple IPs!) and it would not matter which server accepted the data, > as it would be replicated between them all.

The video sounds good. Sounds like a lot of work, but I'm sure it will be helpful. I've browsed some of your existing videos, and they look well done and easy to follow. My current setup has multiple servers, all behind load balancing, so I'm already spreading the load out amongst the multiple servers, and it's working fine, and actually makes it nice when adding/moving servers around. > But to answer your question, yes, it's trivial to tell vpopmail to use > an external database for it's user store.

That's pretty much what I thought. Like I said, while I'm no qmail expert, I have been working with it for some time, and know the ins-and-outs of how it works, for the most part, so this isn't "New" to me, but each OS distribution seems to have slightly different ways of doing things, and that's the main thing I need to get used to.
