If your ISP do not care such a thing, it will logically not publish a
stringent SPF record either.  So you will be able to do all the things like
sending mails all over the world, but you take the risk that you will get a
lot of stupid bounces saying that you sent somebody a virus (like what I'm
getting now).  In my understanding, the beauty of SPF is that it is
completely voluntary.  If you don't want it, just don't publish an SPF
record.  But there are a few exceptions to this, unluckily.

If your university does use SPF, then you'll not care whether your ISP
implement SMTP.  All your mail traffic will directly go to the university,
authenticated.
