That helped a lot, thanks!
Indeed, the Courier mail server had a bug and queried an attribute that 
wasn't in the schema. I've fixed that in Courier's code.

There's a bug in BDB backend, though. As can be seen it doesn't return 
an error code on decoding errors, while Meta backend does. If BDB were 
returning error code on those errors, the problem  with Courier would be 
noticed instantly - Courier just wouldn't work.

The whole filter was hardcoded in Courier's source, it was:
(!(source=*))

The query looked for the "maildrop" attribute.

The filter was incorrect, as the default name of the attribute is now 
"mailsource", not "source", as defined in Courier schema and config files.

Thanks again for your reply! It helped track down that bug in Courier.
