Reply not work for outlook.de

Attempted Reply/Send Failed
An attempt to send or reply from your alias [email protected] was just made from [email protected] which failed because it didn't pass authentication checks and could be spoofed.

In order to send or reply from an alias there must be a valid DMARC policy present for outlook.de and your message must be permitted by that DMARC policy.

The attempt was trying to send the message to the following destination: [email protected]

These are the authentication results for the message:

mail2.anonaddy.me; dkim=none; spf=pass (mail2.anonaddy.me: domain of [email protected] designates 40.92.91.12 as permitted sender) smtp.mailfrom=[email protected]; dmarc=none; arc=pass ("microsoft.com:s=arcselector9901:i=1")

If this attempt was made by yourself, then you need to inspect the authentication results above and make sure your recipient's domain (outlook.de) has the correct DNS records in place; SPF, DKIM and DMARC.

If this attempt was not made by you, then someone else may be attempting to send a message from your alias. Make sure you have a suitable DMARC policy in place (with p=quarantine or p=reject) along with SPF and DKIM records to protect your recipient's email address from being spoofed.
