SMTP error from remote mail server after RCPT TO:<[email protected]>:
host mx.server.ro [xxx.xxx.xxx.xxx]: 550-Verification failed for <[email protected]>
550-No Such User Here
550 Sender verify failed

"Sender verify failed" can have several causes:

- The email account does not exist or cannot be detected - check the cPanel for the email account

- The sender's email account is also configured on the recipient's server - it is a problem encountered when a domain transferred to our servers remained configured in the network of the provider that hosted it previously

- incorrectly configured mail exchanger - if you use an external email service, make sure you have selected in the cPanel "Remote mail Exchanger".

If none of the above applies to you, we recommend that you contact the destination server administrator.
