مساء الخير، أواجه مشكلة\n550-لا يوجد مثل هذا المستخدم هنا\n550 فشل التحقق من المرسل

لقد قمت بنقل حساب من استضافة إلى أخرى
واجهت مشكلة عندما أرسل رسالة، أتلقى رسالة مرتدة تحتوي على خطأ.
n550-لا يوجد مثل هذا المستخدم هنا\n550 فشل التحقق من المرسل
ذهب إلى تقارير البريد الإلكتروني
تقارير تسليم البريد
يظهر هذا الخطأ
ECDHE-RSA-AES256-GCM-SHA384:256 CV=no: خطأ SMTP من خادم البريد البعيد بعد RCPT TO:<[email protected]>: 550-فشل التحقق من <[email protected]>\n550- لا يوجد مثل هذا المستخدم هنا\n550 فشل التحقق من المرسل



آمل أن تتمكن من مساعدتي. لقد واجهت هذه المشكلة منذ أكثر من أسبوع ولم أتمكن من حلها
لاحظ أنني المسؤول الجذر وأمتلك خادم VPS

Make sure the MX record is correctly pointing to the new server.

- DKIM and SPF records must be valid

If mail routing is handled by the new server then set Email Routing > Local Mail Exchanger

On the new server, I created an email account, and it works for sending and receiving
But the carryover account does not
The information you said is that I fixed it and checked the mxtoolbox website
All of them are correct, I don't know exactly where I made a mistake

The picture below is when I transfer a message to it from a second server

These are the bounce messages I receive when trying to send
Note that bounced messages also disappear after a period of time

Note that when I send to Gmail, the message receives and vice versa as well

Is it because of the server??

I'm not sure how the Bad Request error inside WordPress would be related to the 550 email issue - are you seeing multiple problems with the system? If so, please create a new thread for each issue to avoid confusion.
