installing big qmail server ... where to start?

Hi all,

I have to plan and setup a mail solution for about 50.000 users, here are 
some key features requested by our customer:

 - self coded webfrontend w/ webmail and administration (filter, alias etc)
 - 100MB quota per user
 - autoresponder
 - about 50.000 user
 - online backup of data
 - some more featuers for web frontend

Since I happily use qmail for some other (but smaller) installations, I 
want to try it with qmail here for this project as well. My only problem 
is, I have no clue where to start ... beginning from "should I use 2 
redundant and really strong or some more but cheaper servers?" to "which 
qmail distributions and patches should I use (ldap, mysql, ...)?" and "how 
to store data (mails) and do online backup w/o downtime?".

I know you can't give me _the_ solution for this issue, but I am thankful 
for any hints and internet links on this topic.

I am sure you guys can help me :)
Greetings and TIA, Matthias
