We've noticed that Trend Micro "mail-abuse.com" just "assumes" ips are dynamic by default,
because they just assume that working, rfc compliant, reverse dns that just-so-happens to be automatically generated would indicate dynamic ip space.
Sven, Which is it? By default or because it looks automatically generated? By default would seem to be a problem. Automatically generated, not so much. If you haven't made the effort to set up and secure a mail server then you shouldn't be talking smtp to the hosts mail-abuse.com is used to protect. If you haven't bothered to set the reverse DNS to match your server's name then you haven't made the effort, at least not with a modicum of competence. Regards, Bill Herrin -- William D.
