Bounced messages

 When newsletters are not successfully delivered, due to an invalid email address, a mailbox that is too full, or incorrect configuration of sending or receiving mail server, the message will be sent back to the sender by default. The issue must be resolved manually. To help process returned messages, a return path can be added to outgoing mail. The email recipient will see the sender's address, and any reply to the message will be sent to the sender, but bounced messages will be sent to an alternate return path. This must be a mailbox that can be accessed by the bounce processor so that the reason for the bounce back can be determined.

The original message is searched in Wise and if configured and allowed by the customer, the message can be sent via mail instead. This can happen three times, if the email address is not updated. After the third bounce back, the customer will receive an Inbox message in the web catalog requesting that they update their email address. If the customer updates their email address, the bounce counter must be reset to 0. If the customer does not update their email address, the email address is turned off in the system.

In order to prevent OCLC from being marked as a spammer, Wise will send an email notification after two bounces, and the email address is removed from Wise after five bounces.
