      Unfortunately gentoo didn't have 2.1.5 available, so I just made the
      switch to 2.2.5.

      That was just a guess. In my case the LMTPD runs on the same server.
      Unfortunately even when turning preforking off, I still get the
      bounces with codes 2.0.0, 354 and 5.5.2 ...

      I think I need more log output here ... I'll try to increase output of
      postfix and cyrus a bit ...
