Suppose all email addresses have the form "u...@example.com", that the company has two locations site-a and site-b, and that the mail servers are mail.site-a.example.com and mail.site-b.example.com. There is no need to deliver every email message to every mail server. Instead, you set up one virtual alias for every user: us...@example.com us...@mail.site-a.example.com us...@example.com us...@mail.site-a.example.com us...@example.com us...@mail.site-b.example.com user1 will receive all their mail on mail.site-a.example.com, and will read all their mail there. There is no need for complex synchronization protocols. Instead, you use SMTP to deliver mail to the right server. Wietse
