Why can't you just pipe the output of "doveadm altmove" command
through an
external command to do the XZ/LZMA compression if dovecot no longer supports
it internally?
From doveadm-altmove (1):> This command can be used with sdbox or mdbox storage to move mails to

location.
And that's set in stone.
