been reading all your concerns about reverse FQDNS. In my example,
we are a very small firm and I am the IT network admin responsible
for configuring our server. One of the reasons I configured our
server was because we deal with Photography, graphic design and
occasionally presentations of Movies. These are fat files that are
not viable to send thru emails. Our setup is far from being
perfect and does not follow the ISC BIND advised rules of how I
would like to follow to run a proper server. Like two different
networks, one ip address for every ns.mydomain.com and web
services and so forth. Believe me, I would love to do that if I
had the budget for it. Therefore, that is not really my decision
but it falls under the way my ISP charges $$$ for each ip address
and reverse setup. </blockquote>
Well, that means your setup is ok, lookups will go like this:<br>
1 - your.mail.server -> some IP<br>
2 - some IP -> a name in your ISP's DNS, typically very generic
like 2-45-231-6-isp-dynamic-pool.xxxxxx<br>
3 - 2-45-231-6-isp-dynamic-pool.xxxxxx -> back to "some IP".<br>
<br>
The fact that numbers 2) and 3) match and could be done more times
if needed, is what SMTP is looking for. Hence you are not deemed to
be a spammer on that account.<br>

decided to work with what I have and be happy with the limitations
and at the same time try to work around them. I put a lot of
thought in the beginning about the issue of: -Should I reverse my
main NS or Should I just leave it alone since I do not do any
transfer or run any email server from my server. I thought in the
beginning; "Well, no spammer will attempt to relay through my
server since this will be one more reason they will not get things
to work properly." However, this is not really a concern. Like I
said, my set up is not perfect but everything works fine from my
end so far with limitations! …and Yes, I do occasionally have a
very short delay between the main "<a class="moz-txt-link-abbreviated" href="http://www.mydomain">www.mydomain</a>" and "mydomain"
but the same delay never happened with the other domains/websites
I am running under the same ip address. I guess I could reverse my
main domain to my one and only static ip address and my question
would be: - Does that would affect the other websites I am serving
using the same ip address? Thanks everyone for this wealth
discussion!
