Re: Own Public DNS Server

Leythos,
From my understanding, the fact that mail doesn't get through to some
servers doesn't mean they categorize it as spam but simply the fact that there is no "certificate" that indicates its true origin. Maybe I'm wrong in my understanding but, my issue is not really spam. Please let me know if this information matches with your understanding.

Thanks,
Dan

To be fair, 99% of the exploited DNS servers I've seen were misconfigured or
*very* old BIND servers. Any IT admin worth their salt should be regularly
monitor security newsletters and checking their conf files for compliance...

But any IT Admin worth their salt should know that a RDNS is not going
to be the sole factor in your email being determined as spam by most
SPAM detection software.

As an example, most RR Biz RDNS shows IP.central.biz.rr.com or something
close to it, and they will not change it for you, period.

At the same time, proper email headers, proper A/C/MX/Text records will
prevent your email from being detected as spam.

The only time proper records, with RDNS gets you detected as spam is
when your ISP is not really ethical and is on a block/black list, has
issued you a DHCP Pool IP address and told you it's Static, or when
you're running a SMTP server on a Dynamic IP and the range is known to
be a Dynamic IP to the anti-spam services.
