What I would to see (and have never researched in depth) is a way to apply
the blackhole routes on a community to port basis (i.e. we set up a specific
BGP community to filter mail, and that community goes to a route map that
kills only port 25, another community applies to a map that kills port 80,
etc).  When I have spare time, I may see if there is any way to do that.  Of
course by then, IPv6 will be obsolete, so .....
You can ask JunOS to do this. I have yet to figure out a way IOS could do the same.
