Ok, how is he going to know it is a real list and not a new form of spam?
Is there a list of real list servers?
Thanks for understanding the issue.
Maybe, when the auto responder receives an email from a list that the auto
responder and never seen before, it should send the response to the person
that it was addressed to. If they never accept the response, then the auto
responder system will block that list, or at least block it for that person.
But if multiple emails come from the list do not send multiple responses,
your users would not like that!
Very good idea! Do you give me royalty-free license to use that idea (just in
case it is not in prior art)?
At least this way, if a person does forget to whitelist the list beforehand,
then only one member of list will get an auto-response and only once.
Very clever Guy! I like it. Will implement if you post reply giving
royalty-free license to your idea.

The user should have whitelisted the list at the time he subscribed to it.
But humans are not perfect (except maybe you Ralf?)
Guy provides a reasonable solution above in case human makes a mistake.

Again I will repeat (4th time in this mailing list) that AccuSpam is *NOT* a
challenge-response anti-spam system.
The users and owners of anti-spam systems that detect non-existent address by
sending a response could also say to you that mailing list are inherently
broken, if they do not allow generalized SMTP functionality.
Some people (Guy) are interested in solutions. Other people are interested in
being "correct". It is quite clear in life which type of person accomlishes
more solutions.
Thanks,
