Why does MDaemon Connector show "on behalf of" in the 'From' header on messages from an MDaemon mailing list?

When an MDaemon Connector user receives a message from an MDaemon mailing list, the 'From' line shows the list address 'on behalf of' and the sender's address rather than just the sender's name and address.

To prevent the sender header from being added, follow the steps below:

1. Select Setup
2. Select Mailing List Manager...
3. Select Mailing List Settings
   
   
4. Uncheck Add 'Sender: <List>' header to all list messages
