How secure is your e-mail password?

I don't understand why most POP email is still authenticated using
cleartext passwords instead of digest (hash) based authentication
(which doesn't send the password itself but a hash of the password).
Anyone can steal your e-mail password by simply monitoring on a public
network. And why is it that most ISP's don't provide the option of TLS
/ SSL communications?
