Hello everyone,
one of my domain name is : rauhut.eu and I use the offer : PRO
Today I noticed that I'm not able anymore to sent emails from my OVH mail adresses to email recipients at t-online.de.
The error code is always the same:
This is the mail system at host mo584.mail-out.ovh.net.
_ I'm sorry to have to inform you that your message could not_
_ be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.
If you do so, please include this problem report. You can_
_ delete your own text from the attached returned message.

_ 5.1.9 (DKIM reject DKIMr) Missing, invalid or non-matching DKIM signature_
_ (in reply to end of DATA command)_
In the Telekom forum exists already a thread concerning the problem.
[german discussion in the Telekom-Forum
It would be fine, if those two big players OVH and german Telekom will find a solution to this problem.
Tried this?
Configuring a DKIM record
https://help.ovhcloud.com/csm/en-ie-dns-zone-dkim?id=kb_article_view&sysparm_article=KB0058259
I think the error message is in this part:
5.1.9 (DKIM reject DKIMr) Missing, invalid or non-matching DKIM signature_
Please let us know if it resolved your problem.
Also you may want to have a look at my post (link below) that I believe has some useful info and
where I have looked into how to get free OVH e-mail
compliant with the DKIM/MTA-STS, but that is impossible
as OVH offers one e-mail address for free but my e-mails end up in SPAM
folders or rejected because of missing ability to configure DKIM on free e-mail address.
Would German equivalent of this be a car without a dashboard? I can drive it, but would not know
how fast I will be going, what my fuel level is etc. as with the e-mail solution for free e-mail account or e-mail without DKIM I will not know if the recipient seen my e-mail in Spam folder (let's face it, who checks their Spam filter)?

Yes, I tried.
Even for the Pro Mail account I'm not be able to communicate with t-online.de destinations.
It would have been helpful to have more information in your reply .....<br />as "not able to communicate" really does not tell me anything :(<br />but let's try to help you ;)<br /><br /><br />Did you check your settings with:<br /><br />**https://mxtoolbox.com/**<br />check the following:<br />- dns lookup<br />- dns check<br />- dmarc lookup<br />- spf lookup<br />- dns propagation<br /><br />Also run the check on your DKIM for that you will need to enter "selector"<br />which is in your TXT record for DKIM<br /><br />**whateveryouset**.rauhut._domainkey<br />TXT<br />v=DKIM1;t=s;p=MIGf.............QAB<br /><br />SELECTOR = whateveryouset.rauhut<br /><br />So in MXToolBox you enter the following to check (SELECTING DKIM Lookup):<br />rauhut.eu: whateveryouset. rauhut<br /><br />or if only interested in checking DKIM:<br />dkim:rauhut.eu: whateveryouset. rauhut<br /><br /><br />Just a quick check and you have not got a DMRAC set on your domain "rauhut.eu":<br />https://mxtoolbox.com/SuperTool.aspx?action=mx%3arauhut.eu&run=toolpage<br /><br /><br />It's a quick fix, just one TXT entry in your DNS record, please read on DMRAC so you understand how it works. My record is following, but it's important you understand the line fully and you need to subsitute domain.ovh with your own one and create aliases for the following e-mails:<br />a] forensic@domain.ovh<br />b] postmaster@domain.ovh (should have that one)<br />c] dmarc@domain.ovh<br />(you can choose what ever names you want for - forensic@domain.ovh and dmarc@domain.ovh)<br /><br />_dmarc<br />TXT<br />v=DMARC1; p=reject; ruf=mailto:forensic@domain.ovh; rua=mailto:postmaster@domain.ovh, mailto:dmarc@domain.ovh; pct=100; adkim=s; aspf=s<br /><br />But please read on it so you understand what it does<br />#Add your DMARC record<br />https://support.google.com/a/answer/2466563?hl=en<br /><br /><br />and<br />**https://www.mail-tester.com/**<br />(What score do you get when you send the e-mail here? Are there any errors?)<br />[When sending the test e-mail, use HTML and copy a large text into it from an random article :]<br />and you can always share the result if you get stuck with it.<br /><br />What is the "ERROR" message now in the e-mails sent to t-online.de domain?<br /><br /><br />Please let us know if you have managed to solve it and how.
I'm sorry but I forgot to inform the community, that after requesting OVH to set the DKIM record, I was able to communicate with Telekom customers from the one testing Pro Mail account that I own.
@CloudFairy: But thank you so much for your detailed explications. They are appreciated and I'll take them to memory for later need.
You are welcome
