My sent Sympatico e-mails are being blocked. I receive the folliwing Delivery Notification Message:
SMTP protocol diagnostic: 550 5.7.1 Service unavailable, Client host [209.71.212.44] blocked using Spamhaus. To request removal from this list see (AS3130). [Name=Protocol Filter Agent][AGT=PFA][MxId=11BA355B93E7C318] [DS1PEPF0001709B.namprd05.prod.outlook.com 2024-12-18T14:34:09.606Z 08DD1AADD10A3932]
This block of my Sympatico e-mails can only be unblocked by my Internet Service Provider (ISP). This would be Bell. I have contacted the Bell Technical Support team but I have not received an answer to this issue.

There's a problem since yesterday with Microsoft blocking accounts. Had the same thing yesterday to a live.ca account.

Yes. Sympatico credentials are still connected to Microsoft in some cases. Bell used to use Microsoft as their e-mail provider.

The issue has now been fixed.
