Herein lies the problem. We have users outside of the college who are
using an ISP which blocks port 25. Our mail server does not support
port 587, at least that I am aware of. This means we cannot use smtp
auth or use sasl over port 587.
It's not a difficult configuration issue to make it do so in most MTA's.
The college would be wise to do so, because even without SPF, some service
providers won't allow MAIL FROM:<> or From: referencing a domain they
don't host.
