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 :) [1] http://mlmmj.org/ __ http://bogomips.org/unicorn-public/ - unicorn-public@bogomips.org please quote as little as necessary when replying
