I've done this with qmail and vpopmail (although not at that scale) I believe the default vpopmail hashed database should allow what you want in the scale that you want, but if it doesn't, you can configure vpopmail to read user data from a MySQL database. That may be smarter/faster anyway. But either way, the combination of qmail/vpopmail should facilitate that many users. I can't guarantee, however. If you have a test server, install qmail/vpopmail and write a perl script to add 200,000 users and make sure it works first. Also, you can add on IMAP capability. -- Bill Moran Potential Technology http://www.potentialtech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
