Hello, I am required to run through a proxy server when connected from my University campus. I have changed the system wide network settings (in system preferences -> networks) but this change only seems to affect some applications. More specifically, it doesn't seem to affect: Firefox, Mail, python (via mechanize), and ssh and does seem to work for: Safari, Chrome, and Skype. Since, it works for Skype which connects over port 56158 I don't think the University has restricted only port 80 access through the proxy. I have read a number of similar posts about Mail and proxy but doesn't seem like I could find any answers. Thanks.
