[EXIM] Regular expressions for filtering.

With the advent of these new direct injection spam programs I'm trying
to come up with a way of filtering out dialup ports on some of the
larger service providers. Is exim's regular expression filters up to the
job of matching something like this.

sdn-ts-003riprovP12.dialsprint.net

I'm thinking of an expression like *-ts-*.dialsprint.net.

Has anyone tried something like this with sender_host_reject_recipients?
