It's not just the university server. I have a list of about 15 SMTP servers that I could get onto under a normal ISP, but now that I'm on UniversityNet they all block my connection. I'm never harmful when I do this btw. It's all in good fun with friends only. I'm capable of anything SMTP will let you do, define a sender, a reciever, a subject, a message, etc. You can do the same thing wtih netcat, but netcat won't work either when I try this. I refuse to become a script kiddie and use a mail spoofing program.
