Emails to name@murena.io returned - 'failed DANE validation'

Using /e/OS murenacloud
1

Hi,

I am trying to send email to my address: myemail@murena.io from my ISP hosted email account.

However for the last few days they have all been returned, my ISPs failure message reading:**
**
Last reason : 450 4.7.323
Explanation: 4.7.323 The domain mail.ecloud.global failed DANE validation: DANE-EE:
DANE Certificate Association Data does not match client
certificate (SHA2-256)
(client-cert-CN=mail.ecloud.global)

I spoke to my ISPs tech, and they suggested the issue was with the murena.io host.

Any thoughts appreciated.**

Is that an actual problem or some days ago ? There was a certificate problem a few days ago.

took me a bit, I thought it looks fine at first too

apparently the hash announced in the tlsa records is of the whole certificate, not of the pubkey in there (that should stay stable with key reuse over time, to not always needing to update the tlsa record)

(It was a topic many months ago already)

@Manoj if you show this to your mail person it will get fixed - DANE validation fails on e.email / murena.io (#8772) · Issues · e / Backlog · GitLab

this should address the other threads too

The issue has been shared with the infra team to check and resolve. We had an issue with our certificates last week which was resolved. Will request them to check if these messages are part of the same issue or a different error. Will update.

Thank you @tcecyk and @Manoj for looking at this.

Help desk contact and resources noted, I did search on here for ‘failed DANE validation’ - but nothing came up.
I note the MS Server issue, I did use an outlook account to send an additional test email to my murean.io account this afternoon (08/02/2026) but so far not received that email on my murena.io account, or had a delay or non delivery notification from MS.

sorry - but i cannot figure out if/what i can do from a user perspective?
i cannot address all (potential) e-mail servers and ask for update.

what is/will be a soulution go start receiving e-mails again?

thank you and best regards!

as a user you can’t do anything. But the reason is identified, only a matter of hours until an admin wakes up

Pl can you recheck if the error is still showing up. There were some configuration related issues which have been resolved.

It seems like something got fixed. I just received three test e-mails I sent myself earlier today from my Outlook account, basically all at once. Also confirmed that any new e-mails I send to myself from the previously failing accounts also go through. Yahoo and Google were always fine, but now my Microsoft accounts work too. Thanks for resolving this.

WRT Google : in my case I could send emails to my Google account but they landed immediately in spam. This morning everything worked again - sending and receiving emails.

Hi @Manoj received all the test emails in the early hours of this morning, including the MS Outlook email, so presume all fixed, many thanks :slight_smile:
