Workflow Mailer Is Moving Response E-mail Notifications Of A Single User To The Discard Folder, How to clear " warned list" ? (Doc ID 2493367.1)

"If the message is not a notification response, meaning it does not contain an NID line, the notification mailer moves the message to the discard folder and treats it as an unsolicited message. For the first unsolicited message from a particular e-mail address, the notification mailer also sends a warning message back to the sender of the message.
However, to avoid sending unnecessary warnings due to bounced or auto-reply messages, each mailer node stores a list of e-mail addresses from which it has received unsolicited mail, and does not send any further warning messages to those addresses. Instead, if the node receives a second unsolicited message from a particular address, the notification mailer discards the message and raises the oracle.apps.wf.mailer.unsolicited event. You can optionally define a subscription to this event if you want to perform some other action in response to the second unsolicited message. For all subsequent unsolicited messages, the notification mailer simply discards the message.
Note: Each mailer node can store up to 100 e-mail addresses in its warned list. If the node receives unsolicited messages from additional addresses when the list is already full, the notification mailer removes the oldest addresses from the list and adds the new addresses in their place. Also, the notification mailer clears the list by removing all addresses when you start the mailer for the first time, and again whenever you stop and restart its container. In these cases, the mailer may send another warning message if it receives further unsolicited e-mail from an address that is no longer on the warned list."
