This is exactly what we do (as customers rather than suppliers). The most efficient way is to do this with uucp rather than SMTP, POP or IMAP. Two reasons: 1) The uucp connection is only open as long as there's anything to do. This drastically reduces connect time. It can be set to poll however frequently they wish. (We poll 8 times a day & have average connects of 2 mins daily for around 1200 mail items per week) 2) Store & forward of mail is an interchange between a push protocol (smtp) and a pull protocol (usually pop or imap). Pop & Imap are geared to individual mailboxes. UUCP will pull in all the messages and pass them to rmail on the client side which can then farm them out (via sendmail in our case) to whatever mailboxes they want to set up. You don't have to know. You need to establish an MX to client.domain.nu or whatever, then set the sendmail mailertab to pass all mail for this domain to clientdomain.UUCP. Set up a uucp account for them, then you're done. Your clients can then use a unix box or even M$ Exchange/CC:mail (if they're weird enough) to collect it. We've had this system for 3 years now, and it works a treat.
