In Regard to Thanka ec^ha

Be careful.  At least one list subscriber got what looks like a letter
returned to him from the list, indicating in proper form that he is not a
subscriber - he is - but containing a payload for the latest email virus.
It is possible to get subscriber names for non-silent participants from
the list archives, so somebody could put something like this together as a
way of persuading you or your system to open the attachment, or in an
attempt to get you to send the attachment to the list in your own name.

I haven't figured this one out.  It might have been specifically hand
targetted at the person in question or it may be that it was generated as
a side effect of one of the now standard schemes for making nastygrams
look like they are just something coming back to you or, alternatively,
for making mail appear to be coming from an address that is actually
non-existant or irrelevant, but do please be careful about opening at
least bounced back mail from the list, and do make sure that your virus
protection software is up to date.
