When you check a site on this web site the first revdns check can fail and
the explanation is as follow

Reverse DNS entries for MX records
This may be a false positive due to the nasty BIND bug (client side) that

I decided against notifying the recipient for Vulnerabilities. Apparently,
vulnerabilities are essentially spam - and notifying the recipient would
mean that they end up getting an unwanted message after all.

Markus,
The idea is, that we don't want to block VALID email. So, if a reverse
lookup times out, there is no way to determine if there is no valid match
and we can't just assume that it is SPAM.
Time-outs could be temporary problems with a particular DNS server, it could
be a routing problem on
Hi all,
I'm not sure about this, but I've seen some spam messages coming from
domains contained in our sd-file. (hotmail.com) However the messages
hasn't failed the SPAMDOMAINS test.
For example from the Sender-IP: 218.25.255.18
Can it be, because it's not possible to finish the REVDNS-query?
My sentiments exactly! Someone didn't have their thinking cap on straight when
they thought of this. It is just a lazy knee-jerk reaction to a complicated
problem.

Here is something for your weekend list of things to ponder...
I heard from a potential customer (small ISP) yesterday that tried a
Challenge/Response system for 4 hours.
Here is what happened (as best as I can explain it).
He implements the Challenge/Response system.
A few of his users send e
So, just wanted to let you know that you can get messages that skip Junkmail
processing if they come in as you are going down for maint. Perhaps for
scheduled things, there should be a recommended procedure to shut down the
IMAIL services for a few minutes first, until the queue is all delivered
