autoresponder loop

[kilburn]

Ispcp's autoresponder could by improved by logging the responded messages and avoiding multiple replies to the same sender within a time-frame, something that it's not doing right now.

Nevertheless, it injects an "X-Autoreply" header that should be detected by the other autoresponder, and looks for a similar headers on received e-mails precisely to avoid such loops. Therefore, I would say the the autoresponder on the other end is actually behaving even poorer than ispcp's one. If the other end has a reasonable autorepsponder, this situation will simply not happen. Concretely, if you send from an autoreply-enabled address in an ispcp system to another autoreply-enabled address in another ispcp system, no loops will happen.

Obviously, we would be glad if you actually improve the current situation and contribute the resulting code!
