outside of a few very well defined cases where you always need a certain piece of information to move further or where you need to notify someone that some particular action was taken (for example, when someone signs up with me, and I want to confirm that I got the signup and ask for a public key) are canned responses better than no response?<p>right now, my system sends an auto-response when you email the support@prgmr.com address. I'm not sure at all that this is the right thing to do... it clutters up the requesters mailbox and really conveys no info other than "the ticket system got your email" which, I think, can be assumed.
