The NO-SOLICIT SMTP extension described in the Internet-Draft draft-malamud-no-soliciting-07.txt has been implemented in Messaging Server as a proposed standard. The following channel keywords can be used to control this facility:
sourcenosolicit specifies a comma-separated list of solicitation field values that will be blocked in mail submitted by this channel. This list of values will appear in the NO-SOLICIT EHLO response. Glob-style wildcards can be used in the values, however, values containing wildcards will not appear in the EHLO announcement.
destinationnosolicit specifies a comma-separated list of solicitation field values that will not be accepted in mail queued to this channel.
