Yikes! E-mail harvesting possibility?

[Mark Wieder]

Might want to check out The Mail Archive, a free archiving service
used by some other listservs I subscribe to. It obfuscates any
embedded emails, whether in signatures or in headers or in the text of
the emails. Not sure how they manage this, but it's a great way of
making the list archives pubicly available and still protected.
