Well, sendmail with some real crude tweaks, given that the user data do not exist as plain ascii file, but with a database hook to also to determine where the data/usermapping with virtual domains/redirect shall be pumped into the POP-server-storage vie nfs. > > The ServerWorks chipsets have been extremely stable in my experience.

In our setup, when it comes to big numbers, you need big iron, so that you need not to administer some big heap of servers.
