Hi list, please excuse multiple replies from my side to the "Thunder" thread. Every time I posted to the csound list (and I have successfully posted in the past) I did receive an email error messages "Undeliverable", as included below. I did not specify menoche@rci.rutgers.edu in the recipients of my mail and only posted a reply to csound-users. I wonder why I got this message, and if someone else received similar messages when posting. Oh, and there is more tutorial's on Andy's site as well ;) thanks, P Here is the error message return mail: -------------------------------------- annwn25.rutgers.edu rejected your message to the following email addresses: menoche@rci.rutgers.edu (menoche@rci.rutgers.edu) The email address wasn't found at the destination domain.
