Do you have more information available?
Storage: Do you intend for POP users to store mail locally only? Or locally
and on the server? What is the mailbox sizing you're aiming for?
Usage patterns: Is this all in the same time zone with all users
concurrently using the system? If not, how many concurrent are expected?
Message size: What's the average message size you expect?
Generally speaking, SMTP performance is achieved by adding physical disks
especially for submit transactions. Delivery will also have some disk
performance relationship.
POP, IMAP, and HTTP users typically scale quite well and are what the FE/BE
scenario is designed to achieve. My biggest concern in that kind of design
would be around reliability (availability of service) and disk subsystem.
Network topology would be next depending on the requirements.
