        I'm afraid the technology to rapidly sift through large volumes of
information to search for specific areas of interest is widely available. It
is totally reasonable to not want to send mail through your ISP's mail
servers and perhaps directly to a trusted mail distributor over an encrypted
link. Of course, you can easily use a port other than 25 for this purpose.
The problem comes when the recipient tries to validate your origin address
against your secure mail server.
