Thank you for all your help, but I just can't get it to work.
 
What I have now: For some mailboxes I pt extra parameters in the
delivery command (via maildrop):

EXTRACOMPRESS="-o debug_log_path=/tmp/lda-debug-log -o mail_debug=yes -o plugin/zlib_save_level=9 -o plugin/zlib_save=bz2" 

These parameters do arrive in lda:
1. Logging works.
2. If I replace plugin/zlib_save_level=9 with plugin/zlib_save_level=10
   I get the correct error message from the zlib plugin.

There are no problems in the logs and the mails arrive safely.
There is just no compressed material in my mdbox storage files.

Yours
