According to DoveCot Wiki dbox files are re-written by a secondary process. ie delete do not happen immediately, they happen latter as a background process and the whole message file is re-written. You can set a size limit on message files.
Some time ago I email Tim, on a few ideas to make it more ZFS friendly. I.e. to try and prevent rewrites. If you use dbox and keeping snapshots you will eat your disk up. MailDir is a lot friendlier to snapshots, but it will be slower for backups or searching text within the body of lots of email. Ie there are pro’s and cons with ZFS. Personal I will go for snapshots as being more important as I take them about 10 times a day and keep them for 7 days. Also MailDirs are easier to restore and individual email. It comes down to pro’s and con’s. Unfortunate performance is always the most important goal.
