[ExchangeList] Re: Reverse DNS Look-up and Mail

Yes, it most definitely does. Like Bruce stated, if you send an email to me,
I am going to run a plethora of tests to determine if that email is legit,
ham, spam or malicious. Those tests not only check the email itself, but
also check the server it came from, the domain it came from, the IP it came
from and so forth. So, if your sending server does not have a rDNS that is
going to fail one or more tests. If it does not have a correctly formatted
rDNS it is going to fail one or more tests.

Thanks,

 

I got one response that says it should not be affect, and one that says it
should.  Does anyone else want to weigh in?

Yes it does, because I cannot do a reverse lookup to verify it is coming
from you it would get rejected as spam

Thanks.

 

Does this also affect if they can send mail to you?  For example, I send you
a message at the correct email address, but it gets bounced back to me.

If you are sending e-mail from an IP address, you are pretty much required
to set rDNS these days. Otherwise, the big boys (AOL, Yahoo, others) will
not accept e-mail from you. Not to mention that some of the little guys
won't either (like me - I've only got a few 10's of thousands of e-mail
addresses).

Just a question.  How many folks out there have reverse DNS lookup set-up
for their domains to support mail?
