    I haven't tinkered with it long enough to be certain I'm not doing
    something stupid, but I have to admit I've run into similar
    difficult with the LMTP-AUTH. I'm going to fiddle some more with
    that.

    However, with 2.0.11 you can technically get around the LMTP-AUTH
    requirement if so desired, just make sure that either you bind your
    Cyrus lmtpd server to a private network address, or use the
    tcpwrappers support to block unauthorized access. Assuming you've
    got either of those taken care of, you can do something like this:

    /etc/cyrus.conf:

    SERVICES {
      ...
      lmtp cmd="lmtpd -a" listen="[127.0.0.1]:lmtp" prefork=1
      ...
    }

    The "-a" turns off the LMTP-AUTH. The listen parameter can have an
    address like this:

      listen="[127.0.0.1]:lmtp"
      listen="127.0.0.1:lmtp"
      listen="cyrus.example.org:lmtp"
      
    This can be convenient if you have a private network between your
    Postfix server and your Cyrus server. This works with Cyrus 2.0.11.
