The DKIM key is perfectly installed. The problem is that the mails arrive with the DKIM key failing. my records in cloudflare

aaP_caiocesar Hello, I suggest you consult your DNS provider

aaPanel_Kern I'm not using Cloudflare I'm using Contabo DNS, and I've just seen I have the same problem. I think the emails were fine a while ago. Your message is not signed with DKIM.

I forgot: Debian GNU/Linux 10(Py3.7.9) aaPanel LinuxStable 6.8.23 Already tried, fix and restart Dovecot/Rspamd/Postfix

btw: This issue is on VPS1. Everything is fine on VPS2, same config, same DNS manager, but a month older install.

idflorin Hello, please go to your DNS service provider to check whether the txt record is complete, or use this website to inquire https://www.dmarcanalyzer.com/dkim/dkim-checker/ This has nothing to do with the system, and now our DNS manager upload to the dns service has a problem in the test repair.

aaPanel_Kern from contabo: from /www/server/dkim/freelinksubmissions.com/default.pub default._domainkey IN TXT ( "v=DKIM1; k=rsa; " "p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCkj8500WUAGxzFB0gUWASmhQmrxSD7csRdmVBy7v6ff8z6GnYnXJ3cOkbgdbS1AABsH9+vemPYLZLwtPmwzdotr5UdpAdkSStIks+HKKi5lLyMgPul1cVuY873eXyR5DBmBSnH4qtowi0GoVB27cI2RCuaajPEfUL4fSU1GEfxnQIDAQAB" ) ; are the same, still: Your message is not signed with DKIM

idflorin Hello, it is default._domainkey , there is no domain name after it

aaPanel_Kern really? why this works fine on VPS2? ``

idflorin Hello, it is recommended that you consult your DNS service provider.

Hello,
https://support.google.com/mail/answer/10336?visit_id=637998386742274660-1822704968&p=NotAuthorizedError&rd=1

The ip of the server sending mail is 103.156.248.46 you used SMTP relay?
The mx record of the domain name is 103.156.248.127, please make sure that the mx record is the same as the ip that sends the email. And contact the server provider or network provider to do reverse resolution of ip

aaP_jasonfomenky

aaPanel_Kern I have the same problem with dkim. It shows not set when my DNS clearly has all the information set up. Dont know what really is wrong. And my mails dont get signed

aaPanel_Kern

aaP_jasonfomenky
Does the domain name have a relevant dkim record?

aaP_jasonfomenky

aaPanel_Kern Yes it does have a relevant DKIM record. I hard used the mxtool to verify it

aaP_jasonfomenky

aaPanel_Kern
Here is the result

aaPanel_Kern

aaP_jasonfomenky
Is clicking Not Set consistent with the result of the query?

aaP_jasonfomenky

aaPanel_Kern

Yes all what is provided in the query result is what is on my server. Is it a server side problem? Cuz I can’t do anything useful with my mail

aaPanel_Kern

aaP_jasonfomenky
Hi, can you give us your aapanel information? The server makes a snapshot backup first, if possible, please send it to kern@aapanel.com.
It is recommended to fill in the following
Post link:
SSH IP address, account password and port:
aapanel login link address and account password:

No post link will not be able to know which user's information is

aaP_jasonfomenky

aaPanel_Kern Just sent them now, thank you. Will be waiting

aaPanel_Kern

aaP_jasonfomenky
Hello, the records of dns domain name resolution are inconsistent with those of the mail server
