The SERIAL_ALERT notice (RLIST notice prior to 18.05: See Bug 19794) is used to send an email to patrons who have subscribed to the alert service via their account. They are notified when a new issue for a subscription arrives. We have users who have left, and whose emails are no longer valid but who have not cancelled their alerts. These are generating quite a number of undeliverable emails, which bounce back. We know no way of cancelling the redundant SERIAL_ALERT via the Koha intranet other than by an SQL delete which we do not want to risk. Ideally there would be a way for staff to kill off these redundant alerts. Perhaps the alert cancellation could be tied to the borrowers.dateexpiry?
