I've got my school mail setup through SMTP and it won't let me send any messages. It says the connection is fine and will receive mail just fine, but sending doesn't work. I've had it set up this way for about 3 months since I've had my computer and it's worked just fine. It's kind of annoying that I can receive mail just fine, but if I want to reply to a message I have to log in tot he website to send. Any ideas on what could be causing this? And yes I've checked all the obvious preference settings, even deleted the account and reset it up.
