Forced errors
Fails matching deliveries on purpose with a chosen SMTP code and description, and counts how often it has done so.
In detail
Where a pause holds mail, a forced error ends it — but properly: the message gets a result, the result reaches the result queue, and the statistics show a failure with the code you chose. That is the difference from purging a queue through the broker, which loses mail with no trace at all. The occurrences column is unusual and useful: the engine counts matches, so the row itself says how much mail it has stopped. For an operator cancelling a misdirected campaign, that number is the answer to "did it work".
