btw: What are the actual advantages of sdbox over maildir?
- Not moving files from new/ to cur/ directory
- Not renaming files when changing message flags
- Not readdir()ing directories (although maildir_very_dirty_syncs=yes helps a lot with this)
Basically less disk I/O and making it possible to have mailboxes with a huge number of messages without everything slowing down horribly.
I had been wanting to ask about this too...
So... what are the disadvantages?
Message flags are stored only in dovecot.index files, and files get somewhat more easily corrupted than the whole filesystem. Having a separate dovecot.index.backup file helps with this though. Also there's the disadvantages if you can't easily switch away from Maildir because you're using some non-Dovecot tools to access it.
