Primary and Copy
Recipients Indication (P2)
This feature allows you to specify primary recipients and copy recipients of a mail
message. Recipients can be individual correspondents or distribution lists.
Recipient names occupy two records—one for delivery (P1) and one for display (P2).
The use of a distribution list as a recipient illustrates how X400 uses these records:
The TRANSFER delivery system expands the distribution list and uses each
individual name for delivery.
The recipient X400 UA displays the distribution list name instead of a lengthy list
of members.
