Allo! Yesterday, I try to figure how the auto-responder work. I can't modify a message, need to erase it, and replace with a new one. Just annoying! Also, I discover, there is a time limit for the auto-responder to be send, mostly for active mailling list. The problem is this feature is at the domain level, and not at the user level. So, if the same sender, send a message to different users, he received only the auto-response message from the first users. This can be embarrasing for big site with a lot of users. Do you have any fix on that?
