I don't understand why this happens: I get a message from Subscriber1: - I read the message and click Reply. The new message is addressed to: Small Cell Lung Cancer - I read the message and click Reply All. The new message is addressed to: Small Cell Lung Cancer; [log in to unmask] I get a message from Subscriber2: - I read the message and click Reply. The new message is addressed to: Subscriber2 - I read the message and click Reply All. The new message is addressed to: Subscriber2; [log in to unmask] Why the different results? Configuration is set: Reply-to= List,Respect What I think should happen is: - I read the message and click Reply. The new message is addressed to: Small Cell Lung Cancer (or [log in to unmask]) - I read the message and click Reply All. The new message is addressed to: Sunbscriber; [log in to unmask] What else besides Reply-to in the configuration determines who reply messages are addressed to? Any wisom or WAGs appreciated.
