To test SRS, do this:

First, list every external address which any one of your users uses to
forward to their University email account, or which they may use like
that in the future.

For every such address, you need to check that SRS is already working. 

Those servers are outside your control but you can test them -- send a
mail to the address which forwards to the University, and then watch
your own logs to see the sender address of the mail when it comes to the
final destination.

If the sender address is rewritten and looks like an SRS address, and
passes SPF, then SRS is working. 

On the other hand, if _any_ of the mails come back _without_ the sender
address rewritten, then the world has not finished upgrading to EmailV2
and SRS yet, so you should wait longer before implementing a strict SPF
checking policy.

To assist you in this, I've temporarily set up the address sgcarr at
infradead.org which forwards to the address from which you posted your
mail. You can send a mail to that address, then see whether it comes
back rewritten or not. Let me know when you're done testing and I'll
remove the alias.
