Another optional one is needed:
Currently when logging on to an email server the isis.service.email.sender.address value is used as an account username, in addition to also being used as the 'sent-by' email address, if you don't have a choice as to the username this is problematic, such as with Amazon Simple Email Service (SES).
With the additional config parameter, when present this value should override the isis.service.email.sender.address value as the account username, when not present the present arrangement should be used.
