You're limited only by memory ... however, qmail-smtpd reads the whole
file every time it starts up. So you're better advised to put the
first fifteen busiest hosts in rcpthosts, and the rest in
morercpthosts.cdb.

Sure, if you don't mind making all of your email hosts rely on NFS. A
better solution might be to rdist or rsync the files from a master
machine.

Yes.
