subscription to new ML probably working...

[Eric Wong <e@80x24.org>]

I'll migrate everybody else over around 20140514T20:00Z, otherwise you
might get duplicate messages from being subscribed to both lists.
If you're willing to deal with dupes for a few days, you can try
subscribe/unsubscribe/help commands:

	unicorn-public+subscribe@bogomips.org
	unicorn-public+unsubscribe@bogomips.org
	unicorn-public+help@bogomips.org
	(help will tell you the rest)

Stop reading here unless you're interested in implementation details :>

I only have mlmmj configured to handle the +commands, outgoing SMTP,
and bounces.  It does not receive normal list traffic like a standard
mlmmj install.  Instead, I have it configured to replay data from ssoma
every minute, so I used (as the mlmmj user):

    NAME=unicorn-public
    URL=git://bogomips.org/unicorn-public.git
    ssoma add $NAME $URL "command:ssoma-replay -L $HOME/spool/$NAME"

Where ssoma-replay is a tiny shell script which reads from stdin:
------------------------------8<--------------------------
#!/bin/sh
MSG=$(mktemp -t ssoma-replay.orig.$USER.XXXXXX || exit 1)
cat > "$MSG"
exec /usr/bin/mlmmj-send "$@" -m "$MSG"
------------------------------8<--------------------------
This means it should be easy to have outgoing SMTP on a different server
and allow other folks to run the same service.

Other notes: mlmmj has defaults I like out-of-the-box (unlike mailman,
ugh).  However, archive retrieval with mlmmj is rather painful,
but we have public-inbox and ssoma :)
