How to whitelist incoming "Sender Verify" checks



المشكلة :

دومين محدد يظهر فى track delivery انه rejected رغم انه لا يصنف spam

وتم عمل ريستارت services و فك lock عن الايميلات ولكن rejected

Sender verification checks are performed on your server for incoming email and these checks help prevent unverified/spam email from arriving at your server. However, sometimes there may be a sender that you must allow email from even if their configuration does not allow for these checks to pass.

Ultimately, the sender will need to address these issues, however, you can temporarily allow their email to come through by enabling the following options in your cPanel & WHM server.

حل المشكلة :

المشكلة عند المرسل وليس من السيرفر الخاص بك ولحلها من خلالك يجب وضع استثناء للمرسل
WHM >> Service Configuration >> Exim Configuration Manager
Within this section you will want to search for the following options:

اولا :
Sender verification bypass IP addresses
IP addresses for which to bypass SMTP-time sender verification checks



ثانيا :
Trusted SMTP IP addresses
IP addresses exempt from all SMTP sender, recipient, spam, and relaying checks. IP addresses you enter here are stored in /etc/skipsmtpcheckhosts. These senders must still use an RFC-compliant HELO name if the Require RFC-compliant HELO setting is enabled.

These options will allow you to enter the IP address of the sender you wish to exclude from these verification checks.



ملحوظة : قد يكون الاى بي متغير الذى يرسل منه الايميل اى يرسل من اكثر من ip لذلك يجب وضع جميعهم

وكذلك hostname قد يكون متغير عند وضعه.
