</div>Cyrus IMAP can do (1) and (2)<br>
<br>
(3) Your MTA (Postfix) should queue messages for delivery, and you should<br>
be able to deliver them on demand after fixing a quota problem. That's how<br>
I work, but using Exim as the MTA.<br>
<br>
(4) Cyrus doesn't have web based user management. However, you don't really<br>
need that. Cyrus IMAP will create a mailbox if you try to deliver email to<br>
a new user. Make sure that Postfix rejects email for unknown users, and<br>
you'll be fine. There may be third party solutions for deleting users,<br>
managing quotas, and so on. The usual thing is to use a command line tool.<br>
<br>
(5) You can use your regular file system backup tools to back up Cyrus-IMAP<br>
mailboxes. Emails are stored in separate files, so incremental backups are<br>
very efficient. It's possible to use delayed expunge to ensure that all<br>
emails are backed up, even if they arrive and are deleted between<br>
incremental backups.<br>
