When a mail group is created and a recipient has an alternate (non-default) email address which is used for purposes of the list, once the list is saved, the entry for the recipient changes to the default address rather than the chosen alternate address. For example, if an individual has both a home and work address with the work address as the default, how can a list which needs the home address be forced to retain the home address rather than reverting to the default work address when the list is saved?
