I could use some help with clarification of the following :
A MS whitepaper on FE/BE Exchange topology states - "...if you are using SMTP (on a front end server), a mailbox store is required, but the mailbox store must not contain any mailboxes" The reason for this is that SMTP requires a mail store for routing of NDRs.
***What is the exact configuration of the front-end server where a private store is mounted but has no mailboxes?***
I was under the impression you HAD to use SMTP on the front end for the whole FE/BE thing to work. What I need is to generate NDR's and support SMTP/IMAP/HTTP (OWA) clients.
Thanks for any insight!
