When you create a recipient mailbox, the system delivery failure rule is copied
as the first regular rule into list of rules for the recipient mailbox.
By default, the following keywords are used in the Delivery failure keywords
keyword group:
Delivery Failure
Undeliverable
Returned mail
Unknown Recipient
Delivery Report
You can add words to the default keyword list, but do so with caution. Words in
different contexts (such as unknown) in the keyword list for the delivery failure
rule can cause valid e-mail to be routed as undeliverable. In this case, use
specific phrases instead of individual words.
When you create a mailbox, it is automatically assigned a delivery failure rule,
which is copied from the system delivery failure rule.
.
The default settings for the system delivery failure rule are:
use the e-mail default skillset, EM_Default _Skillset
use keyword group delivery failure keywords
Installation and Maintenance Guide
CAUTION
Risk of routing failure
The intention of the delivery failure rule is to route undeliverable
contacts.
If you change the properties of the rule, you affect the behavior of
the system delivery failure rule, which affects all recipient
mailboxes you configure in the E-mail Manager.
If the skillset associated with a system delivery failure rule is
deleted, the default skillset, EM_Default_Skillset is used as a
substitute.
If the EM_Default_Skillset is deleted, the system stops processing
e-mail messages.
