Hello everyone, a rather unexpected thing happened the other day, someone subscribed to a list of ours with an address that uses an autoresponder, which of course creates a perpetual loop...he recieves a message from the list...autoresponds to the sender (list address)...recieves his own message and autoresponds again. I had thought that this was a very unlikely thing to happen...but its happened, luckily I caught the situation early, but even so, we still jammed 200 useless messages down everyones throat which caused a large number of unsubscriptions and complaints.
Does anyone have a good way of dealing with this problem....I know it will raise the usual furor about munging the reply-to header .... but forcing the reply to go to the sender and not to the list is an option that I already know...are there any more please?
All the best David Kelly

If the autoresponder strips all header lines there aren't any easy solutions. You could write a script which records submissions to the list with a timestamp. If there are too much postings from one sender within a certain time range assume it's a loop and unsubscribe the address. E. g. if there are 10 submissions from the same address with the same (or similar) subject arriving within 50 minutes it's most probably a loop.

This sounds like a very good solution... unfortunately, writing scripts isn´t my strength...does anyone have a script already written that does this and is willing to share it with everyone? (eg. publish it in the list?)
