I plugged qmail-ldap in an earlier message, but in a previous life^H^H^H^H job we deployed Communigate Pro (on Solaris)-: and it was rock-solid and handled pretty heavy loads without burdening the server much. Good responsive online tech support and bug-fixes, feature additions. IMHO their web gui's a bit ... uh... primitive, but it's useable. At another ISP we supported, we deployed Mirapoint mail appliances and they were fine too, but I don't have much direct hands-on experience with them. Both are worthy commercial offerings, and I think better than most other commercial alternatives. Check communigate's web for some interesting tech-rag reviews and comparisons with other products. I would definitely advocate some kind of fault-tolerant architecture, whether it's tight clustering, loosely-coupled federation (qmail-ldap with shared NFS mailstore), or whatnot. Email's dead critical to users and you can't afford downtime. It's really sweet to be able to take down one MTA/SMTP/POP/IMAP/LDAP box in the middle of the day for an upgrade, and have no one notice. :-)
