Well my two cents... To do it "right" (my definition may be different than others) and if cost is no object and you want scalability:
Set up a SQL server system to manage the user accounts. This is separately scalable and can be load balanced/clustered on it's own. You may even want to use Oracle on a sparc box for this. It can be done. Set up NAS for the mail files. Then it can be shared and load balanced as needed as you grow. Set up a system for the Imail system to do the SMTP/POP3 stuff, you can then add multiple systems easily to use the database for the users and the NAS for the data. You can then load balance across those systems. You can also easily add things like declude, IMGate, etc into the mix as you see fit. Anyway that would be a good way to do it. Plus side too is you can put all of that on a single system and separate it out as needed and budgets permit.

I have the impossible task of setting up a mailsystem for 500,000+ users.... With about some 10,000s simultaneous connections. I believe IMail is able to do the trick, I only try to figure out the best configuration. Of course, an external DB is much less troublesome when you want to mod or del users. Would it be possible to split the IMail program from the userfiles: Use a couple of NLB servers for the server+webmail and a couple for SQL userDB and mailstorage? BTW: this is an open invitation to any of you to suggest the best possible configuration for this many users.
