Benefits to a front-end server include: - offloading processing of SSL - makes firewall configuration easier when you have multiple mailbox servers since a front-end server keeps the HTTP, POP or IMAP session rather than redirecting it to a mailbox server - pretty much required for doing load balancing of those protocols - allows you to move a mailbox between servers without having to reconfigure POP and IMAP clients

I believe front-end servers can also host mailboxes even though that doesn't make a lot of sense architecturally.

Sent: Wednesday, July 17, 2002 12:39 PM To: Exchange Discussions Subject: RE: Front-end Servers So, if I wanted to take my new front-end/back-end setup and have the front-ends setup for routing inbound/outbound mail - I can do this via setting up smtp virtual directories. Current setup is (2) fe's and (2) be's with load balancing on the front-ends. I have a virtual IP & Name in DNS for a single point for the NLB to the front-ends. Testing: since I have my last 5.5 server handling the smtp at the present time, can I setup the smtp virtual directories to handle some test mail so I can ensure that email is capable of being routed properly. I have (2) unix box's that route all incoming email to the smtp server for distribution and no plans to change there duties. Anyone do this type of setup, yet...
