Why not ask her to change this? If someone is blocking your email for a reason, we won't give out info how to bypass it.
That's fair enough if she wants to block my own email address, but she presumably has not realised that she has also accidentally blocked all our roomies/flatmates (and our visitors) at the same time. They are all blaming me for that, and my ex-friend is probably wondering rather miserably why none of her old flatmates ever write to her any more. She went abroad and email had been the only way of communication, so none of us can tell her what she's done.
