RAV was using addresses available in message headers, it was ignoring
(!) all command line args. No wonder some of recipients (like Bcc: which
is an empty header) was dropped. No wonder that the sender address was
changed - From: address was used, not the original $sender_address.

I contacted Gecad Software again telling them about the problem (now
they couldn't say it was because I was using Exim 4). They should have
uploaded an update that should use command line arguments.
