Thanks for the link, looks pretty sensible in their setup. I don't think this rule is a good idea: http://www.wsrcc.com/spam/bounce.html [quote] 550 Client host rejected: cannot find your hostname, [168.126.3.59]; Here the sending site's DNS administrator forgot to put the name of the host into the DNS system at all. Our system has no way to tell the name of your host. This is probably the most common mistake. There are two places the DNS administrator has to enter the information for each host. One, the so called "forward mapping" maps the hostname to IP address. Two, the "reverse mapping" maps the IP address to the hostname. Both of these mappings have to agree for our host to believe the information it gets.
