If you're looking to handle this many mail accounts, I'd strongly
recommend you use multiple servers. PCs aren't that expensive,
especially since you don't need super-fast CPUs; you do need multiple
fast drives and a decent network connection.
If you had a "server farm" with (say) 10 PCs, you don't have to worry
about UID limits, even with versions of Unix that don't support 32-bit
UIDs. You also don't have to worry about putting all of your users out
of business if one server goes down, and chores like backups become much
easier.
I don't know much about proxies; is there some nifty way for a user to
connect to a large mail-server, have the server tell the user's machine
"your mail is actually on server03", and then redirect the POP/SMTP
requests to the correct PC without having all of the resulting traffic
pass through one machine? This would allow you to load-balance by
moving mail accounts around without inconveniencing the user.
