I have a request for an improvement to Listserv. This morning I sent a private e-mail for which I had set my Reply-to: to my LISTNAME-REQUEST address. As it happens, one of the addresses I sent to had an old-style responder which auto-replies to *every* message it receives, rather than responding only once to any unique address within a certain time interval. Well, it responded to my LISTNAME-REQUEST address, which itself sends out an automated REQACK1 template message, so they got into an infinite loop. I knew to insert .QQ into the REQACK1 message to break the loop. The loop was taking 3 seconds per cycle, and I was able to break the loop after a mere 400 exchanges had occured. If I had not noticed the problem by downloading my mail again soon after the loop had started, I and those who also receive my LISTNAME-REQUEST mail may have received several dozen megabytes of looped mail. I regret that some people still have obsolete, reply-to-every-message autoresponders. But upon reflection, their softeware is only half of the problem. I'd like to request that the auto-reply process of Listserv's LISTNAME-REQUEST addresses match the procedure of modern autoresponders that respond only once to any unique address within a certain time interval, specifically to prevent mail loops. Thanks for your consideration. -- Roger Burns, listowner
