Looks like it solved the problem. David Relson, thank you!

So the default postfix mailbox_size_limit value 51200000 does not allow
bogofilter to work (confirmed by other Postfix + Bogofilter users).

Dear Wietse Venema, is it possible to change the Postfix default
and/or describe this problem in Postfix and/or Bogofilter FAQ?
