That sounds familiar.  We have a soft record (ending ~all) because we
never told all our users that they could not send mail via ISPs with
their columbia.edu sender address.  Once in a while, some place will
decide to reject mail anyway if it does not come from our specified
servers.  So having no SPF record is better.  ?!  Come to think of it,
it's been a long time since that happened.  That's how dead SPF is.
