    Hi all, I'm new and I'm a newbie. I'm completely new in cPanel: we have a site that send email from php function, and from september, we have this problem:

    Code:
    This message was created automatically by mail delivery software.
    
    A message that you sent could not be delivered to one or more of its
    recipients. This is a permanent error. The following address(es) failed:
    
      xxx@somedomain.it
        SMTP error from remote mail server after MAIL FROM:<user@crystal2.servernamehere.net> SIZE=2682:
        host liberomx4.somedomain.it [212.52.xx.xxx]: 553 #5.1.8 Domain of sender address <xxxxxx@crystal2.servernamehere.net> does not exist
    
    ------ This is a copy of the message, including all the headers. ------
    
    etc etc
    
    I have searched in forum discussions, but I don't found solution for my problem.

    Anyone can help me?

    Thanks all

    ps: I don't have access to WHM.

    Hello,

    To resolve your issues you will have to use SMTP mail function in your site setting instep of php mail, On remote server sender verification is enabled and due to that they are rejecting your mail because you server is sending the mail from cPanelUser@serverhostname account and it's not present on your server.
