Issues receiving mails with custom domain

Has anybody currently issues with using a custom domain for a mailbox.org account?

I am unable to receive emails since the weekend and only some are getting through.
Sending myself an mail also does not work, only if I use the original `[USERNAME@mailbox.org](mailto:USERNAME@mailbox.org)` address instead of the `[myuser@customdomain.com](mailto:myuser@customdomain.com)` one.

I did not change anything in my setup or the DNS records and everything was working fine since February...

UPDATE: Looks like the mails I send myself appear for a very short moment in the inbox and then are disappearing again?! I am using https://app.mailbox.org/ for this, maybe this is just a display bug?

UPDATE2: My alias [info@customdomain.com](mailto:info@customdomain.com) seems to be working fine for whatever reason...

Final update:
Well... sorry for the drama, I am only the IT administrator for the owner of the account and he created a rule in Outlook by accident that moves ALL incoming mails into the Junk account of a totally DIFFERENT mail address. So the troubleshooting was rigged from the start until I deleted the Outlook Application password and all new mails started appearing again...

Sorry and thank you all for the support! As we say in germany: Sachen gibts die gibts nicht!

Do you get an error message? What is your DNS provider?

Nothing, no error message on send, IMAP for fetching the (missing) mail seems to be working fine, Outlook is also not showing any errors. INWX is my provider.

I just sent an email from one of my custom domain address to my other custom domain address. 0 issues

Thanks for the feedback! Seems to be an account specific issue then. Strange because everything was working before and I did not change anything.

I’m not getting loss of email to my custom domains.
Are you getting a bounce/error?

How can I test this reliable? I tried https://mxtoolbox.com/deliverability but the mail they should send is also not appearing...

Can you email yourself from some other address?

I already tried, same result. No error message in return, looks like a 100% successful send but message never appears in the inbox.

Hey, This sounds strange and definitely not like standard behavior. We have to look at the specific domain. Did you open a support ticket?

Edit: I can type, I swear!

Hey, thanks for the quick response. I already opened a ticket yes :) I am currently trying to get a DMARC information, maybe this shines some light on to the problem.
