Solved Problems receiving email

[AlexanderNL]

I'm currently experiencing the following problem.
I can send emails, but not receive them. It's a dedicated server with multiple email addresses. This problem has likely been occurring since Thursday or Friday, but as far as I know, nothing has been changed on the server.

I've now forwarded my email to my Gmail account, but even there, nothing is coming in.



The strange thing is that I can send emails from domain name 1, but I don't receive any. These are stuck in Mail Queue Administration.

If I send an email from domain name 2, an email address has almost the same information. The only difference is that other domains use CloudFlare and this one doesn't. The MX and NS information are otherwise almost identical.

Below are the details from Mxtoolbox.
Domain 1
Domain 2

It seems like the email is coming in, but it's not being delivered to the inbox. Even when I try to email via RoundCube, I can't email myself from domain 1 either.
The only update I haven't been able to get is the latest version of MariaDB 10.6.21, but I don't think this has anything to do with the problem.
I've already adjusted the NS zones, which didn't help either; there aren't any updates anymore. So now I'm wondering where else I can look.

Hopefully someone has ideas where I can look for a solution

All looks fine as for e-mail and domain settings for domain 1.
You might want to check your Exim mainlog and rejectlog to see what might be happening. Maybe panliclog too.

So as what now look like was the problem:
DashboardDNS ManagementMX Records:

Options​

Use this server to handle my e-mails. If not, change the MX records and uncheck this option.

This have to be selected on my server, never seen this option, but this was first solving the most problems for now.

You're welcome.
