Major November 8, 2026 Mailsend Issue 11h 50m Mail services

- investigating Nov 08, 2026, 07:53 AM UTC
We are currently experiencing issues causing mails sent to Outlook, Hotmail, Live and MSN recipients not being delivered. In order to fix this, you can enable your standard one.com DMARC record in just a few clicks in the Control Panel: 1. Log in to the one.com Control Panel. 2. In the menu on the left, go to Domains & DNS. 3. Select DNS records. 4. Under Standard DNS settings, click Show all. 5. Locate the record TXT _dmarc.yourdomain.com. 6. Enable the toggle next to the DMARC record. Please note that DNS changes can take up to 90 minutes to become active across the internet. Once the change has propagated, email delivery to Outlook and Hotmail recipients should return to normal. We also strongly recommend adding an SPF record if one has not been configured yet. If your DNS is managed by another provider, add the records there. You can also follow our step-by-step guides: - How do I create a DMARC record: https://help.one.com/hc/en-us/articles/360015855998-How-do-I-create-a-DMARC-record - Add an SPF record: https://help.one.com/hc/en-us/articles/115005595945-Add-an-SPF-record
