A first try to copy the > existing mailbox "thorsten" to "thorsten_neu" leads to the following: I think I've posted my "Cyrus::IndexFile" perl module to the list before, but I'll attach it here as well. This allows you to parse through indexes a lot more efficiently, and 'cyr_dbtool' (see the patches at http://cyrus.brong.fastmail.fm/) is great for seeing the contents of mailboxes.db. Unfortunately, most of our tools are only for cyrus 2.3+. We were running a fairly recent CVS even back when I started work on dbtool, and that was one of my first projects at FastMail. I've had to do the same job, and I did it by reading the directory contents and listing UIDs via IMAP, then removing any that didn't match. There's no need to move anything. $imap->select("INBOX.Trash"); ls /var/spool/imap/b/user/brong/Trash/ You'll need some logic to map from mailbox names to on-disk paths of course, but I think this is a cleaner solution than the copying one, and as other people have noted, this doesn't break flags (including \Sent) Bron. ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
