DMARC authentication problem

[thien_nv]

Hello every one,
i am using proxmox mail gateway 6.4-3.
I have a problem when other people send mail to my server.
I check the Tracking center and get the notification.

Jul 21 08:56:17 gateway postfix/smtp[8692]: EDFB2142AD9: to=<mydomainn.com>, relay=mail.mydomain.com[ip]:25, delay=1.4, delays=0.01/0/0.15/1.2, dsn=5.7.0, status=bounced (host mail.mydomain.com[ip] said: 550 5.7.0 Message rejected per DMARC policy for sender_domain.com (in reply to end of DATA command))

It looks like the email is reject by policy DMARC
I have added sender domain to whitelist but not fix the problem.

Can someone help me?
Thanks & Best regards,

It look like it's not PMG rejecting the mail, but your downstream server (mail.mydomain.com[ip]) - you need to configure this server to accept mail from your PMG

I hope this helps!

Có vẻ như không phải PMG chuyển thư mà là phần hạ lưu máy chủ của bạn (mail.mydomain.com [ip]) - bạn cần phải định cấu hình máy chủ này để chấp nhận thư từ PMG của bạn.

Tôi hi vọng cái này giúp được!

Thanks for @Stoiko Ivanov.
i am using mdeamon. I have tried disabling SPF DKIM DMARC authentication from sender.

hope this solves my problem.

The message failed authentication tests and is not DMARC compliant, as shown by this error. Both the SPF and DKIM verification checks failed in a DMARC Compliance failure. Because inboxes cannot check the validity of your email, these errors can have a detrimental influence on email delivery.
