    I'm still having problems and appear on at least one block/black list.
    My registrar is WSWD.net and the name servers are currently ns1/ns2/ns3/ns4.private-rack.com .
    My website host is InstaFree (dal.private-rack.com).
    I can't find any documentation that says the wswd nameserver pointers are correct or not.
    I've gone back through all the initial emails received and it appears my email client is set up correctly.
    Using dnsstuff.com free tools, a domain lookup shows all my data dedacted.
    Doing an IP lookup for my shared IP address never completes a response.
    The same is true for a reverse IP address lookup.
    Does anyone have a better tool to diagnose the rDNS issue?

    Hi Jim,

    I hate to say, but you are going to be spinning your wheels with the rDNS. With shared hosting, in which you don't own the IP address, since it is shared by hundreds of users, your domain will not have a rDNS entry. It can't, because every IP address can only have 1 rDNS entry. You can't have hundreds of rDNS entries on a single IP.

    So the server IP (.18) sends mail for every domain on the server. That IP address has the appropriate rDNS entry, pointing to dal.private-rack.com. That is the only rDNS entry that is needed.

    So as I said a few posts ago, if the error on their end is that the rDNS entry is missing, they are completely incorrect. It has to be something else, perhaps an internal blocklist, etc. I can attempt to contact their administrator if you let me know who it is, but no guarantees. A lot of places blacklist huge blocks of IP addresses for absolutely no reason. There is no outgoing spam on any of our servers, and hasn't been for quite some time.

    Bryan,
    I appreciate your comments, and the more I learn the more I understand how complicated successful email communication is these days. I'll list some domains I am blocked from below. One of the frustrating parts of this is that when messages from my @thegoodeshome.com domain are blocked, I can log into my @gmail.com and resend the messages and they go through. Know domains blocking my emails:
    @tx.rr.com
    @hotmail.rr.com
    @efji.com
    @jcpenney.com
    I've tried reaching them with no success. What are the secrets to contacting these domain administrators?
    Jim
