You're saying that because the caret is a beginning of line anchor?  The
web page says: "In the text boxes below, add one address per line; start
the line with a ^ character to designate a Python regular expression.
When entering backslashes, do so as if you were using Python raw strings
(i.e. you generally just use a single backslash)."  I took that to mean
that the caret was a flag to mailman indicating a regex, and would not
be seen by the regex engine.  I'll try a regex which assumes the caret
is passed as a normal beginning-of-line anchor.
