Others have made suggestions on how to cause these messages to be delivered to another machine or bounced, however... qmail is pretty good about handling cases like this. Normally, each message will be tried on the usual delivery schedule, which uses a scaling (geometric?) backoff algorithm, so messages that have been sitting in the queue waiting for this ISP to come back shouldn't actually interfere with delivery of newer messages to responsive hosts. Are you certain you actually have a problem, or are you just worrying when you needn't?
