Question hotmail.com; dkim=fail (body hash did not verify)

[Piekielko]

I have properly configured mail. Works fine in Gmail and other email servers but not in Hotmail...
My mail serwer: Postfix.

The source of the message:
Authentication-Results: spf=pass (sender IP is 163.172.74.76) smtp.mailfrom=horyzont.com; hotmail.com; dkim=fail (body hash did not verify) header.d=horyzont.com;hotmail.com; dmarc=pass action=none header.from=horyzont.com; Received-SPF: Pass (protection.outlook.com: domain of horyzont.com designates 163.172.74.76 as permitted sender) receiver=protection.outlook.com; client-ip=163.172.74.76; helo=mail.piekielko.com;

dkim=fail (body hash did not verify)

After migration DKIM verification fails: dkim=fail (body hash did not verify)

I have read and updated it, everything is correct, but the problem still occurs



Could this be the same problem?
DKIM signature fails at hotmail/outlook (body hash), passes everywhere else · Issue #892 · PHPMailer/PHPMailer

Just my 2 cents: Hotmail may still reject your mails because of the Time-To-Live (TTL) of your DNS record (86400 seconds in your case), their servers have probably cached your old invalid DKIM record. So before continuing the troubleshooting I'd wait for 24h and then check if the problem still persists.
According to MXToolbox your DKIM record is valid, btw.
