Hi, Jeff,

Your second answer is what I asked. Thank you. I'll
test it later. However I think I should still explain
it more clearly here and it maybe of some use.

I have 2000 email customers of the same domain. I want
1000 accounts on the 1st email server and another 1000
on the 2nd server. The reasone is simple, one server
cannot cope with 2000 users.

This can expand to three or more servers. I'm just
curious how yahoo.com, aol.com, msn.com do this. They
cannot make 30,000,000 users on ONE server, right?

Best regards,
Stanley
