We need to be able to provide multiple email addresses for Partner communications and notifications. We should be able to provide a comma separated list of addresses as defined by IETF RFC 5322.
Both SI and SFG email fields are currently limited to a single address entry (eg. firstname.lastname@example.org), and further, we are unable to use @localhost as a valid address to use local system aliases to expand the communication list.
Both SFG account emails (EMAILID in YFS_PERSON_INFO) and SI Community and Entity email addresses (multiple EMAIL_ADDR in YFS_ORGANIZATION) are impacted by this. Our custom Business Process communications are also affected by the limitations imposed by the single email address.
