Is that really such a big concern with confirmation requests though? The mail account aught to be available immediately. But, for the cautious, we could give it a time limit. For instance, if a bounce comes back (again, a bounce, not an autoresponder, even though we're not sure how we'd identify that!) within 5 minutes then the corresponding pending message will be dropped. Fatal bounces return almost immediately. Transient ones take a while, right? (I may be wrong about the above point, but... ) I still like the idea thus far. We could even send a "your message has been deleted because it bounced" message immediately just in case a valid sender was having mail problems or something. -- Jesse Guardiani, Systems Administrator WingNET Internet Services, P.O.
