Date: 2012apr18 OS: Linux Product: mailman Q. How can I post a message with mailman without mailing it in? A. Mailman come with a program called "inject", that can do that. Its probably not in your path. Use it like this:

/usr/lib/mailman/bin/inject -l MY_LIST MY_MESSAGE.TXT

Where MY_LIST is the name of your mailing list. And MY_MESSAGE.TXT is file holding a mail message you want sent out. It should have From:, To:, etc http://www.ietf.org/rfc/rfc0822.txt
