After a long night of debugging and network sniffing I had to
learn, that the problem was NOT the cyrus imap server, but 
wireshark :-(

The pop3 sessions in question have been pop3/ssl sessions, so I used
wiresharks feature to decode this SSL stream (I am running the server,
so I have access to the corresponding rsa key).

Decoding of the first three or four pop3 request/response pairs
obviously worked, but after the "RETR 2" command from the client,
wireshark only printed data sent by the client - data sent by the
server simply was "hidden" in wiresharks output.

Thanks for the great hint concerning "telemetry" - the telemetry logs
showed the *complete* pop3 session, with everything as expected :-)
