Mailman is perfect for this application and I have set one up at http://luther.hostingrails.com/mailman/admin/members_bcsdsta.ca
We are having a problem with a lot of our mail being bounced. It is a small group of 150 school managers who used to get their listserve mail from bcstsda.ca.
Is there anything we can adjust to make the listserve look like it is coming from bcstsda.ca
instead of luther.hostingrails.com/mailman so that all the spam filters won't automatically bounce our messages?
