Perhaps I'm misunderstanding you, but are you referring to 'primary' and 'backup' mail servers, such as the those you specify in DNS records? If so, this doesn't really have anything to do with IMAP. When a mail server attempts to deliver a message to foo.com, it checks the DNS records for foo.com, which contains a prioritized list of mail servers. If it can not connect to the primary server, it then attempts a connection to the mail server with the next highest priority. If a backup SMTP server receives email addressed to foo.com, it will periodically attempt delivery to a higher-priority mail server. The mail will be delivered to the primary mail server shortly after it goes back online. You should not have to actively 'resynchronize' the two servers. You might also want to read up on the ETRN command, which will cause a backup mail server to immediately deliver all its queued mail. -- Christopher Farley www.northernbrewer.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
