Well, an interesting thing happened today - an email from ringsurf
acknowledging the activation of a ring was rejected due to
a spf policy violation. It appears that ringsurf sets the
MAIL FROM to the email of the ring owner, and that was not
allowed by an SMTP server. The message was fatally rejected.
I was surprised to find that the spf record is already
being enforced.
