Server response: 550 550 Verification failed for The mail server could not deliver mail (mailgun & compute-engine)

when I send from [email protected] to [email protected] over smtp.mailgun.org I got this eroro:

"Failed: [email protected] → [email protected] 'RE: test mail' Server response: 550 550 Verification failed for The mail server could not deliver mail to server_name. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries. Sender verify failed"

but when I send from gmail.com to [email protected] or when I send from [email protected] to gmail.com

the mail sent and delivered success.

can you tell me why.

Note: I'm using Google compute engine and WHM.

The error (which is called Sender Address Verification)

I go to

WHM: Main >> Service Configuration >> Exim Configuration Editor >> Standard Options >> Mail

then put

Sender Verification Callouts -> off Sender Verification -> off

Then everything is working fine.
