I've read through this, and I've found all my issues answered, and no 
new issues other than the following minor ones:

1) In Section 3, "The COMPRESS Command", third paragraph, I would 
personally change:

    If the server issues an OK response, the server MUST compress
    starting with the first response after the CRLF ending the OK
    response.

to:

If the server issues an OK response, the server SHALL compress 
starting with the first octet following the CRLF ending the reponse.

2) I would move the fourth paragraph "For DEFLATE (as for many other 
compression mechanisms)," to the normative section.

3) I would try to clarify the last paragraph, something like:

When COMPRESS is combined with TLS or SASL security layers, the order 
of processing data to be sent SHALL be to first COMPRESS, then SASL, 
and finally TLS. When receiving data, the processing order MUST be 
reversed. This ensures that data is compressed before it is 
encrypted, independent of the order in which the client issues 
COMPRESS, AUTHENTICATE, and STARTTLS.

My intention is to avoid any grey areas concerning whether, for 
example, TLS handshaking is compressed or not.

Dave.
