When enabling the Users In Multiple Groups functionality and a sender selects a Send from group all the associated Group Setting should be used. Currenty the following settings are defined by the senders primary group and not the selected Send from group:

• Enable the following identity authentication methods for recipients
• By default, use the following method

This makes it possible for a sender to select a group which is intended for signatures meeting specific regulatory requirements (with a set of allowed authentication methods) and then still be able to select a non-approved authentication method as these are read from the primary group instead.
