Old server to new - 451 Temporary local problem

GoWilkes
I've moved my site to a new server (both semi-managed servers belonging to me), and changed the DNS and A records on the old server to point to the new IP. A few times a day, though, the old server sends an email to me as "root"; mainly updates on cron jobs, and the rare occasion that someone is still seeing the old site through the old server. When this email is sent, though, I'm not getting it. Instead, I get this: Delay reason: SMTP error from remote mail server after RCPT TO:: host example.com [987.65.43.21]: 451 Temporary local problem - please try later
(Where 987.65.43.21 is the IP of the new server.) Both servers have the same SPF record: v=spf1 +a +mx +ip4:123.45.67.89 +ip4:987.65.43.21 -all (Where 123.45.67.89 is the IP of the old server.) I found a thread from 2008 on this error that said to make sure that the domain is in /etc/localdomains. It's not, but it is in /etc/remotedomains, which is where I think it should be at this point since it's now on a different server (but I really don't know the significance of these files). Any other suggestions?

    Servers don't have SPF records, domains do. Are you decommissioning the old server or is it still being used?

    I recognize that domains have SPF records; I was trying to say that the account on both servers has an identical SPF record. The old server will be decommissioned at the end of next month. I'm leaving it online long enough for slow internet providers to update their DNS records. The local cable company (Charter) has been known to take up to 6 weeks!

    I'm not sure I understand why you'd edit DNS on the old server, instead of editing the nameservers at the Domain Name Registrar to point the domain to the new server? You might check the domain for issues here: /http://www.intodns.com/ And check for clues here, on the old server that's not sending email: WHM " Email " Mail Delivery Reports

    I edited both. Changing the DNS on the old server showed up almost immediately, but like I mentioned before, it can take up to 6 weeks for the nameservers on the domain name to show up globally. The only warning at intodns.com was: Your SOA EXPIRE number is: 3600000. That is NOT OK I'm guessing this is the default set by cPanel, though, since I've never changed it. And maybe the reason some internet providers to take forever to update?

    I found several of the emails in Mail Delivery Reports, but it didn't really give me any more information: Event: defer warning User: root Domain: Sender: root@example.oldserver.com Sent Time: Mar 23, 2014 4:19:04 AM Sender Host: localhost Sender IP: 127.0.0.1 Authentication: localuser Spam Score: Recipient: email@example.com Delivered To: Delivery User: account Delivery Domain: example.com Router: lookuphost Transport: remote_smtp Out Time: Mar 23, 2014 4:19:04 AM ID: 1WRdcU-0008AB-LE Delivery Host: example.com Delivery IP: 987.65.43.21 Size: 569 bytes Result: SMTP error from remote mail server after RCPT TO:: host example.com [987.65.43.21]: 451 Temporary local problem - please try later
    I don't know if it's being rejected from the new server, or if it never makes it from the old server? I do know, though, that it sends a firewall report to my Gmail, and that's going through just fine, so it's either this specific account, or potentially the fact that the account exists on the both servers?

    Hello, You may want to update the DNS on the old server and set it to Remote Delivery instead of Local Delivery. That will update the settings and make sure that the domain in question (or hostname) is not in /etc/localdomains but in /etc/remotedomains.

    Great suggestion, Peter! I changed it, and I'll find out in about 2 hours whether it worked. I'm betting it will.
