I think you missed the point. :-) The idea that I think he's trying to push is that using a single big NFS server for your backend mailstore isn't even close to ideal, and that you can accomplish the same thing by using: 1) multiple smaller mail stores, which do not use NFS for message transfer, 2) POP/IMAP as a frontend for message retrieval, and 3) MX boxen that act as an incoming mail gateway that do the `local' delivery onto the mail stores. The trick to having customers not know on which mail store they live is to use a POP/IMAP proxy that knows where they live and connects to the proper machine when the username is supplied. On the MX side of things you can just use sendmail's aliasing rules to have messages stored on the right mailstore. This tends to be more scalable than an NFS solution. > BTW: Can you give me a little bit more information on your mail server > setup and the protocol you wrote? Not that I want to speak for Gary, but I think the above should clarify things a little more (I doubt he wrote a delivery/transfer protocol for his mail system). -bjc To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
