That may not be so easy. in fact there is no archive of that list, but haven't
archived messages not been processed by mailman?

luckily exactly this message has been posted on one other list i have access to:

what is grabbing my attention here is that there is no text in the From: field,
only the blank email address. digging little further reveals that the text that
gets merged originates from the members name field with which that address is
associated in mailman.

thank you very much. i appreciate it. i will send the originals to you when
this email doesn't help.
