More comments about the document. The draft doesn't explain what to do if the same fax messages was sent to multiple recipients with different rendering capabilities. Should it downgrade for the least capable recipient? Or should it use RSET and start multiple mail transactions to differently capable recipients? Correct me if I am wrong, but it seams that extending VRFY command is more appropriate for the purpose than using RCPT.
