In the beginning of September 2003 a national realty company (kw.com) started
checking incomming email for reverse DNS settings to help stop spam. They
report that most of the spam has been blocked. Only a few companies that did
not have any reverse DNS settings had problems but those companies have fixed
them thier dns settings. Is there a way that Raq550 owners can block Email from
servers with no reverse DNS settings?
