Relay control in SIEVE ???

Hi,

        Does sieve have control on relaying of mails at SMTP?

        When I went through elvey's proposal on "refuse". Good one!

        dontrelay :

        Administrator of the domain can decide to accept the mails 
        but they donot want to relay mails to other. This requires 
        an extension "dontrelay" in sieve .

        Please share your comments on this.

        ======================================

        Syntax : dontrelay <reason string>
        
        SIEVE implementations that implement the "dontrelay" action have
an
        identifier of "dontrelay" for use with the capability mechanism.

        Capability name: dontrelay
        Capability keyword: dontrelay
        Capability arguments: N/A

        ======================================
        
        Shall I come up with formal draft ?

        Thanks in advance for your comments.

        Sincerely,
        MG
