    I'm putting this in the email section because the DNS move may have nothing to do with this?

    The problem: My users are unable to send to att.net and I'm unable to send to outlook.com (hotmail.com) . I get a error that we're blacklisted and I check the blacklist.com site and I'm only on the squid one. It says that it doesn't influence black listing. I'm thinking that they're having a problem because I changed the IP of both the clustered DNS servers that I had. I moved them from one account to another and had to change IP addresses.

    I'm not sure what to do. The main domain of the system has a SPF1 record via the IP and dns

    domain.com TXT "v=spf1 ip4:x.x.x.x (server/host IP) +a +mx +ip4:x.x.x.x (DNS IP) ~all"
    and I just added this for good measure:
    domain.com TXT "v=spf1 -all"

    I know DNS changes take "48 hours" to update but I want to make sure I have the correct settings before I just sit and wait.

    The DNS cluster move lasted 6 days. I moved 1 Server and waited 2 days then moved the other and waited 2 days. I didn't think this would be an issue? The IP address of the cPanel server did not change.

    Lots of Info there. If the IP your clients send email on has changed and is now being blocked, the new IP may have been used by someone before you and got it listed, somewhere. ATT and Hotmail should be responding with a blocked message of some sort. I'd be looking for that I think. With a new IP, you might need to contact them (ATT & Hotmail) and verify you're the new owner of the IP.

    It has not changed. The only IP(s) that changed are the (clustered) DNS server IPs. That is why I'm not sure it has to do with this problem, but that's the only thing that changed. I know the emails to ATT worked before the DNS change as that user sends email daily.

    Still,
    Emails from ATT say more than this, what do they say, exactly, to do?

    Like I said I added the records just to make sure. I filled out the form to whitelist or say "the issue has been fixed" and it's now been the 3rd day and still cannot sent to either.

    I've edited your post, no need for all of that.

    You should remove any manual changes you've made.

    If the server is setup properly, and the clients domains are setup properly, no manual changes as you mentioned, should be needed, IMO.

    When you get things back to stock, and configured properly, check your domains for issues:
    intodns.com

    Thank you for the edit. I wasn't sure what you were looking for so I figured the more information the better. I haven't made any changes which is what's odd. Like I said I added a SPF record just because. So I guess this was never working on the server and it was just brought to my attention?

    The intoDNS checks out ok. All green or blue items. There was a SOA problem but I lowered the number to about 2 weeks.

    Once you're sure you've got things on your end setup proper, and you've followed the instructions having to do with blocks on their end, there is nothing else you can do I don't think. Wait for them to contact you back? I guess.
