German Telekom refuses emails sent from OVH mail server to t-online.de destinations

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._

_ The mail system_

_ : host mx02.t-online.de194.25.134.9] said: 559_
_ 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.

It would be fine, if those two big players OVH and german Telekom will find a solution to this problem.
