i am considering changing my mailbox format from maildir to mdbox. the reason for this is mainly, b/c i have (a) multiple large mailboxes with tens of thousands of mail files, and (b) most of these mails files have a size significantly smaller than the sector size of the disk.
so, since the emails themselves are only about nGB large, the disk space used is at least twice as much, if not even three times.
i know, hard disk space is 'cheap', but still...
Also think about iops. rsyncing 10GB of small files takes a lot longer than 10 1GB files.
but then i read at
https://doc.dovecot.org/admin_manual/mailbox_formats/dbox/
the following:
[...] you must not lose the dbox index files, as they can’t be regenerated without data loss.
I have read this also, and was also worried about this, but when I look at the flat m.988 file, I still have quite a lot of useful data there.
