I had and still have the ORPort on 443.  I had DirPort on 9030, but have 
since moved it to port 80 so that I can put up the Tor Exit explanatory 
web page (DirPortFrontPage).

So what do people do about spam via webmail?  Blocking ports 80 and 443 
largely negates the point of being an exit node.

Thanks for the reply.
