As followup to my own post, I believe I have solved the problem. I
have found that the following data excerpt is required in order to
handle the " and $ characters in the body of email:
data = # Exim filter\n \
if \
${quote:${rxquote:$h_From:}} matches "(abuse|support|staff|admin)@$domain" \
then \
save /dev/null \
endif
The ${rxquote:} handles the strange characters such as $, and the
${quote:} makes certain that any unbalanced "'s don't impact the
lvalue expansion. If I missed this somewhere, I apologize for
repeating the information.
