While it would be "nice" in the real world to do this, many email servers can ALREADY reject mail that does not have a reverse DNS entry, but I have found in practice (my business is an email consulting company) that there are SO many sites out there that do not have this properly configured that business who serve customers cannot afford to ignore mail that comes from sites with no reverse DNS entries. Having SA check for DNS entries for the mail server is one thing (and often results in higher scores for legitimate sites who are just clueless - but I usually contact them and tell them they are clueless <g>), but I would probably see my "false positives" increase to about 30% (up from less than 1%) if I worried about SA blocking these. I would pull my hair out.
