I filled out the form. I don't think my problem was due to NDR so I don't know if they will process it as the form looked like that was what it was centered around. Lets hope that fixes it. Thanks so far...

Question
Why has my server been added to a black list for "policy violation, unacceptable generic PTR record".
I have an SBS 2K3 Premium server. It works great with no issues other than this black list problem. About two weeks ago I started getting delay notices from the server saying that some messages hadn't gone through. After checking my server black list status I realized it had been added to one list @ http://www.spamcannibal.or
My static IP address is 67.141.224.179. I've contacted Windstream to try and update our PTR record but I'm not sure I'm doing it correctly. Please note that our incoming email goes through Trend Micro's Hosted SPAM service before arriving at our server. I only have issues sending to certain addresses. Right now its Bellsouth addresses. My actual mail domain is mail.dmxm.biz.
I've also tweaked the IMF on my server to make sure we weren't sending out Spoofed NDR's.
Thanks in advance.

Go to the site below and do an mxlookup for bellouth.net, recored the IP of the first server. (this is the ip you enter on the AT&T form above)
http://www.mxtoolbox.com/i
OK now from your exhcnage server telnet to port 25 of the ip recorded above (instructions on link below) and you should get an error message. This is what you put into the AT&T form for revelant lines, this error should also include the ip of your server.
http://support.microsoft.c
For changes on AT&T form i typically enter other and type in new email server.
Ok. I submitted another instance with the below information. Hopefully that will help me. Strange thing is though I'm still listed with SPAM cannibal and can't figure out how to get off of that list.
550-67.141.224.69 blocked by ldap:ou=rblmx,dc=att,dc=ne
The tel net message was 550-67.141.224.69 blocked by ldap:ou=rblmx,dc=att,dc=ne
I never got a message from them that it was taken off the list however I did get a notice from MXTOOLBOX that it had been removed. I've signed this server up for their free monitoring service.
After filling out that form from AT&T you should get an email from them that your server IP has been removed. Typically get this email within a day. If you telnet are you still getting the same error? If so and you have filled out the request you might consider emailing them to see if there is a problem with your request , the email address is at the bottom of the att page.
You should at least get a response from att about your request. Do you still show up on any of the blacklists?
http://www.mxtoolbox.com/b
Run a DNS check for your domain at http://pingability.com/zon
Looks like now you are using Trendmicro service, hopefully this has taken care of your problem. You might also want to look at your firewall and make sure no machine are sending out email via smtp. I have seen desktops with viruses send out email and cause the external ip it shares with the mail server to get blacklisted.

A couple of different things. Yes your ISP should be able to setup a PTR record for your server. If not the other option is to also relay your outgoing email through Trend or some other service. Bellsouth (AT&T) has gotten very aggressive with their block list. Fill out the form on the site below and they typically remove your IP from the list with 24 hours. Just don't be surprised if its back on the list in a few months.
