We recently switch from up-imapd to dovecot But many users are reporting that they cannot access certain mail folders. The log file has: imap(dws): Sep 14 00:06:19 Error: File isn't in mbox format: /home/research/dws/mail/TaskDL The files in the logs are "MBX mail folders", not "ASCII English text" as are the folders that can be read under Outlook. Can anyone tell me how to fix this? This is a serious problem in switching. I've read the FAQ and documentation but it doesn't speak to this specific problem. Thanks in advance, Anne Hammond Tech-X Corporation

One file contains all the mailboxes, so expunges may still be slow. johannes

Do you mean some folders are in the UW-IMAP proprietary "mbx" format (essentially an mbox with extra indexing information included)? If so, you'll need to convert them to plain "mbox" files, using something like UW-IMAPs "mailutil" command: mailutil copy <rooted unix path to folder> "#driver.unix:<rooted unix path to new folder>#' e.g. mailutil copy `pwd`/mbx-folder "#driver.unix:`pwd`/mbox-folder" then rename/delete the original folder and move the new one to replace it.

This is a serious problem in switching.MBX is a special UW-IMAP mailbox format. Dovecot can't read those. You must use a UW-IMAP tool to convert the MBX file back to a regular MBOX format. Any UW-IMAP should contain such a tool. Hope that helps. Best Regards Michael Paesold
