Banks can use outsourcing for their mail, that's fine, but they should 
seriously consider the implications. It's fairly obvious that most banks 
don't.

There are things that an email outsource & bank can do together to keep 
things secure - and OBVIOUSLY secure, but it's clear that neither most 
banks nor email newsletter companies actually understand email enough to 
be using it in this way.
