In addition: thanks to password re-use practices, which are epidemic,
"giving provider $X a password so that they can POP email from provider
$Y" is semantically equivalent to "giving provider $X passwords to
some/most/all other accounts of other descriptions".  Even if we
presume the most scrupulous behavior by $X and its personnel --
and history shows that is often naive and dangerous -- it still
increases the exposure/risk of the password in question.

I have the same issue.  Personally I don't care, but I can see that a
surprising amount of the mail is stuff the recipient probably wanted.

I've been encouraging my users not to forward their mail, and if they want
to consolidate it at Gmail or Yahoo or whatever, set the other service up
to do POP retrieval.  Works fine, at the cost of a slight delay in getting
some of the mail.

Better tell your lawyer it's too late.
