I imagine that the OP is BCC'ing the messages to self. I may be wrong or
presumptuous because I BCC all messages to myself, which makes me inclined
to think along these lines.

Writing to file is both laborious and an unorganised way of handling
information. Encryption to self would work wonders. I recommend PGP, which
is free and robust. The best practice is to never include sensitive
information in E-mail. E-mail is unpredictable and not secure. It's like FTP
or HTTP. Because some clueless sites post passwords in plain text, I made
the habit of choosing separate, simpler passwords for third-parties,
so-called 'Mickey Mouse' services. Never remain too uniform security-wise,
e.g. sticking with similar passwords for your Web site and Digg. Script
kiddies can sniff packets.

Best wishes,
