Hi all !
I have been asked to connect 3 sites of excahnge server (one is UK one is US on in IL)
later on those exchange (or one of them) should handle pop3 and SMTP to the world not just internal.
I need suggestions on how i should do it cleanly and secure, i got the picture that only one should be connect to the pop3/ smtp and be the main DNS and a recipent or followup of other mailbox to other sites should be done ....
open to suggestion !
