    Testing our transactional emails sent from AmeriCommerce against SpamAssassin rules, every email is being tagged with points for a host with no reverse DNS. http://spamscorechecker.com

    I would like to thank everyone for their input. AmeriCommerce has created the Reverse DNS Records for our Web Servers to point to americommerce.com. Thank you, David Blount

    The subsequent forward lookup verifying the PTR entry is still not working. 174.143.73.233 --- PTR Record ---> americommerce.com americommerce.com --- A Record ---> DOES NOT MATCH (174.143.73.233) Feel free to test it here: http://ipadmin.junkemailfilter.com/rdns.php

    This has been corrected. http://www.debouncer.com/reverse-dns-check FCrDNS test result: 174.143.73.233 resolved to smtp4.americommerce.com. smtp4.americommerce.com resolved to 174.143.73.233; rDNS if forward confirmed.

    I made one more change for cleanliness on our side. 174.143.73.233 is still showing as failing on http://ipadmin.junkemailfilter.com/rdns.php but it looks like it is cached. Currently every IP address that was not hit by this service is working. Just to double check i tested it in another FCrDNS validation site which can be found in my previous comment, and it passes.
