Hello Everybody a little bit about my situation. I currently use a Kolab Server and my ISPs Mailserver. Since my ISPs Mailserver has a nearly 100% Uptime, a lot of Storage Space and Automated Backup. I want to use it as storage space for the kolab's imap data. The problem is that I only have access to my ISPs Server via Imap. So my question is: Is it possible to tell cyrus to store the mail not on the local machine but on my ISPs Imap account. I saw that it's possible to introduce a new partition to cyrus in the imapd.conf and than tell the process to use this as new storage location for certain users via "renamemailbox user.foobar.mail user.foobar.mail newpartition". You now know what I am looking for and I am open for other ideas.
