No idea. I would use some homegrown script which checks the size of the
pop mailboxes. I wouldn't want to depend on some flaky OS limitations.
You'll never know which system call will bite you.

A 740 supports 32767 in the local passwd. I would go with a different
authentification service though. We have good experiences with LDAP.
Replication is easy.

Yes NFS.
Depends. With multiple ethernet devices 100mbit full duplex should be
enough if the pop3 servers are properly distributed. A NetApp supports
gigabit ethernet if needed.
