i have a query regarding mail server load balancing
i found that yahoo.com has 3 smtp servers handling the email traffic.
this means that any of the 3 servers can handle the mail for a single user say
now when that user logs in through yahoo mail ( IMAP )
how is all the mail retrieved from all the 3 servers simulataneously
i mean to say some of the mail will be in server1, some in the second server and so on
is there some technique in linux to achieve this
