We use a few of these: http://mail-toaster.org/ ...with two clustered Barracuda 400's in front of them. We have all filtering turned off on the mail servers themselves. However, if you are just starting out, you could use the filtering on the servers, and then upgrade to a different solution as revenue increases. With a couple days worth of code writing, we have a single interface that allows us to do pretty much anything. Support: - one click user password retrieving/changing - RADIUS user management - managing any/all domains and/or user(s) - one click to enter any user webmail (to delete large messages for those on dial-up) Administration: - adding domains/users - one click user management/domain management - client level domain management access (web) We have ~10,000 email accounts, and we process very close to 1 million emails per day. We started out using Unix accounts and mailboxes, but that quickly got too cumbersome to manage across an ever increasing number of domains and aliases. With this setup, the front line support staff can pretty much do anything regarding our users/domains safely, that I would have to do myself before. OT, I would also recommend djbdns with VegaDNS frontend. This combination is extremely easy to get up and running, especially after done once. It is an exceptionally fast server, and with the web front-end, makes it a cake-walk to manage domains. This too has client level domain DNS management (per-domain, group or user delegation).
