Maybe. I forget the exact context, but in some places exact matches
and regular expressions can both be users. In that case you need to
start a regular expression with '^'.
Aside from that, in Python regular expressions, you don't need the
backslash on the '-' or the ':'; they only have meaning as operators
inside a complex construct ('-' for ranges inside  character
classes, and ':' as part of extension syntax for () groups). Also,
there's no need for the ".*" at the end
I believe Mailman automatically makes the match case-insensitive. The
only other thing I can think of is that it's legal to use TAB
characters (or none at all) between the ':' and the "Yes", so (as I
wrote before) I would write the expression as
> I have a separate server for spamassasin and not using an extension like

OK, so the incoming mail should have the X-Spam-Flag in it, and this
regular expression should do what you want.
