Note that that's 64K for all domains, not for each. Each user on
your system maps to one unique system userid -- which currently has
a max of 16-bits on most(?) Linux systems. See "man getpwent"
where uid_t is an unsigned int...
Or, you can go the virtual route of storing all user info in some
directory storage like LDAP -- as what Victor mentioned
previously. Mailbox locations, passwords, etc. are looked up
from the directory. With this setup, mostly likely you'll be
using only one system userid for all your virtual users. No
16-bit limit, therefore unlimited number of users. Some links
you might want to check out:
- LDAP_README of the Postfix distribution
- qmail-ldap: http://www.nrg4u.com/
- ISPman: http://ispman.sourceforge.net/

These are used by sendmail, not the POP server. Without these,
your SMTP server won't know to which local user an incoming
e-mail is for -- specially in cases (your example above) where
you have multiple and same username parts but with different
domains.
