A short while ago I thought I would create an email based chat/message
list for former classmates. I want to protect their privacy by not
publishing their email addresses. I started out creating a email address
like
li...@example.com and had that forward to a script for processing.
In the script I strip the original message headers; create a new message
from
li...@example.com, and mail it (Bcc) to everyone on the list. That
way all messages and replies appear to come from
li...@example.com.
Simple and secure enough until people forward messages or attachments to
li...@example.com, then the original distribution and from information
becomes viable.
My question: is there a simple way to scan for and obscure any headers
that expose people's email addresses? Besides, From:, To: , Cc:, Bcc:,
Reply-To:, Resent-To:, Resent-Cc: what should i be scanning and
obscuring? Or does anyone have a better suggestion?
