the migration from maildir to mdbox is a few weeks in the past so I
don't remember correctly. IMHO I migrated from maildir with disabled
zlib to mdbox. with mdbox, zlib was active the hole time and it is still
active. Here is my doveconf -n output: http://p.bastelfreak.de/l2wq/ .
Do you need anything else for debugging?
