Admin Moderation

All messages to be sent are stored in a "to be moderated" area and either must be approved from the web interface or by a list moderator, who receives a request-to-approve email message from Lyris List Manager for every posting. The message that the moderator sends back to must contain both the "message number" to approve the specific message, as well as the password which corresponds to that person's From: address.

This is a fairly secure method of protecting your mailing list. The main way that a malicious person could break through this protection would be to have a "TCP/IP packet sniffer" on your TCP/IP connection (perhaps in your office network) and try to see the password that you have. Then, the person could theoretically use your password to approve future messages.

If you are concerned about this type of security attack, you can take some simple steps to prevent it. First, set your list up to not send moderator notification messages (no member set to "receive moderation notifications"). Then, when a message needs to be approved use the web interface to approve it. For additional security, use a web server that supports Secure-HTTP, so that the web interface communication is entirely encrypted and cannot be "sniffed".
