I would like to move RFC 3848 to Draft Standard, so I am collecting information for the implementation report. Please let me know if you know of implementations (MTAs/MDAs) that generate such parameters (in particular ESMTPA/ESMTPS/ESMTPSA/LMTPA/LMTPS/LMTPSA) and clients that parse Received headers and analyze/check the corresponding WITH parameter values.
Sun's MTA generates any/all of these as appropriate.
