I would like an email auto-responder to not auto-respond back to the same person twice.
I went to my webhost webmail and set an auto-responder. I tested it by sending an email to it. The auto-responders just blindly replies back with an auto-response irregardless of whether it had auto-responded back to that email or not.
Don't you think that is dangerous? Because if someone else sends me a mail with an auto responder turned on. And I have my auto-responder turned on. They would just auto-respond back and forth hundreds of time until the mail quota is reached or the server goes down. Isn't it?
How can I get a "smart" auto-responder that does not auto-respond to the same person twice?
