How many mailboxes could one expect on a system with the following specs Receiving messages via LMTP and only supporting pop for retrieving email. front-end systems would be running exim, proxypop3d, apache and DNS back-end systems would only have cyrus. There would be a third system to provide every thing else..
How would this scale.. how many front-ends to back-end machines.. is there a rule of thumb. I would guess every user would think there mail was important and hit the pop server every minute.
Frontend Pentium 4 2.4GHz No Harddrive drive (remote boot) Localfile system in ramdisk.. 1 gig memory or more.. Dual NICs. (one inside private and one outside) running linux
Backend Pentium 4 2.4GHz Scsi-Ultra-fast drives 1 gig memory running linux
MySQL/Fileserver/Utility system Auth File systems from frontend systems. DHCP DNS Master NFS BOOTP murder (I think I need one of these right?) etc..
