That's solvable, but it doesn't help.

She can send you email at derek at ihtfp.com once, and when your replies
all come from:

  From: Derek Atkins <lkjasdflksdlkjp2338tnlsdfh848492-hds8fs0D at ihtfp.com>

then when she replies to you, she'll be sending encrypted emails.  But
there's another problem.  Anybody can send her email like this:

  From: Derek Atkins <kljasdfoiu347323h3478239-guoHFDH at completely.different>

and she can't tell which is the real Derek -- and she may even start
sending her replies to that address, since any gobbledygook address is
as good as any other one.  But, but, but... letting her know she's
talking to the right Derek is a big part of what encrypted emails are
supposed to provide.
