We've done a simple trick to get this to work. We have front-end postfix servers, with virtual tables set up like this: [EMAIL PROTECTED] [EMAIL PROTECTED] Then the user simply log into the imap/pop server with dom-domain-user, and lives happily ever after. This also makes it trivial to move mailboxes around on different servers etc, even spreading single domains over multiple servers. If you cluster your cyrus servers you don't even have to worry about the user being pointed at the right imap/pop server. The database is being put in a MySQL table, with fallback to a stored backup in a db3 file. MySQL servers are being run with a primary, and slaves on each of the mailservers, allowing speedy local writes. Should the local MySQL server fail, postfix simply queries another. Should all the MySQL servers fail, then we enable soft_bounce on them, and point to local db3 files allowing service to continue. Add to this multiple installations of the postfix frontend servers, all of them able to deliver to the correct cyrus backend using LMTP, either locally or over the network. Sounds good? (at least that's how things are supposed to work when things are done :) Terje Elde Combitel Networks AS
