That's how I work, but using Exim as the MTA. (4) Cyrus doesn't have web based user management. However, you don't really need that. Cyrus IMAP will create a mailbox if you try to deliver email to a new user. Make sure that Postfix rejects email for unknown users, and you'll be fine. There may be third party solutions for deleting users, managing quotas, and so on. The usual thing is to use a command line tool. (5) You can use your regular file system backup tools to back up Cyrus-IMAP mailboxes. Emails are stored in separate files, so incremental backups are very efficient. It's possible to use delayed expunge to ensure that all emails are backed up, even if they arrive and are deleted between incremental backups. > > Regards, > P.
