Hi, Philip!

Mlmmj can do what you want already, I believe. Just add a subscriber of the 'nomail' type using the -n option to mlmmj-sub or by sending mail to listname+subscribe-nomail@domain.tld. Nomail users can post to the list, but posts are not distributed to them.

See the third paragraph of the description here:
http://mlmmj.org/docs/mlmmj-sub/

And the help list text (which you get by sending mail to listname+help@domain.tld) also contains information on this (though in source form, not the most readable):
http://mlmmj.org/hg/listtexts/file/904ef6171308/en/help

Best regards,

Ben.

I've been successfully running a handful of small mlmmj lists for several months
now, on an eApps centOS cloud server, running sendmail. I have a question/request
related to a feature that I used to exploit when working with the old majordomo
mailing list tool:

When using majordomo it was possible to configure a "closed" list, in terms of
senders and receivers of posts (functionally similar to how mlmmj works using the
"subonlypost" control file), while at the same time it was also possible to
configure a secondary file (containing addresses) that could only submit posts,
but not receive any posts.

Perhaps a simple example can illustrate how this might be used:
Acme Services is run by a board of directors, and the board has their own closed
mlmmj list.  There are also several dept managers that work for Acme Services, and
the board would like these managers to be able to communicate directly with all
the members of the board by simply sending an email to the board list. On the
other hand, the board doesn't want the managers receiving any of the board list posts.

There are several other scenarios that might benefit from this ability - in fact
I'd say it might find many uses, and the varied possibilities are likely the
reason majordomo had this feature.

I haven't seen anything that indicates this is somehow currently possible with
mlmmj, so I apologize in advance for missing the notes on how to do this
currently, if its already available.

With mlmmj, I could envision having another directory similar to the existing
"subscribers.d", that would contain file(s) of addresses that only had permission
to "submit" posts.

Or perhaps there could be some way to flag or code files contained in the existing
"subscribers.d" directory that would indicate if the addresses it contains are
only "submitters" or only " receivers" or both "submitters and receivers".

I haven't looked under the hood far enough to know how simple or complicated this
might be to implement with mlmmj (assuming its not there now) so I'm just sharing
the thought, in the hope that someone might be intrigued by the idea of adding
this feature, and hoping it would not be difficult to implement.
