I am running "mdbox_rotate_size = 100m" for approx. a year now on a small server (a handful of users, only). All mailboxes are around 1G each with a lot of attachments. I never had an issue so far.
How much space are your mdboxes using, compared to to quota usage?
Sorry, but I do not understand your question.
I.e. how much space is wasted on deleted messages?
(not sure this will be easy to measure, because of compression..)
True, it is hard to answer ;-)
As a very rough estimate I do estimate a 5% waste of space regarding deleted messages. But, my handful users are very disciplined in purging their deleted messages on a regular basis (I told them to do), and thus my regular "doveadm purge -A" runs will reduce that amount of wasted disk space to a minimum.
Not very helpful, I know, Michael
