There are two types of Network Delivery mailboxes:
A Network Delivery mailbox:
makes it convenient for local subscribers to send messages to remote subscribers. The remote subscriber has a local mailbox number and the remote subscriber's name appears in the local directory
has a recorded spoken name, a spelled name, and can appear in the Company Directory. It also contains the site number and mailbox number of the remote recipient. In the case of AMIS addressing, it contains the system access number and mailbox number.
is an alias for a network address. This type of mailbox does not contain any messages, and cannot be opened for message retrieval.
NOTES:
If you access a Group List message from a Network Site mailbox, AMIS addresses are not included in the message envelope.
Take these precautions if you set up a remote Group List as a target for a Network Delivery Mailbox:
Do not send messages to a Group List that includes a Network Delivery Mailbox whose target is the mailbox you sent the message from.
Make sure that you do not have any Group Lists that send messages to each other through a Network Delivery Mailbox. For example, a Group List that contains a Network Delivery Mailbox that forwards the message to another Group List. This Group List also contains a Network Delivery Mailbox, and this Network Delivery Mailbox forwards the message back to the original Group List.
If you set up a Group List where either situation happens, a loop occurs where a single message can generate many copies of the message.
