    I'm trying to set up a business email, so I made a new email adress via my cpanel.

    I managed to add the mail to my mac mail app client, but I can't send nor receive emails.

    Whenever I send an email from my personal account, it doens't arrive.

    Whenever I send an email from my bussiness email, I immediately get a mail that says:
    Mail delivery failed: returning message to sender

    This is what is says in the mail:

    (P.S. I switched out the actual email with name@bussinessemail and
    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:
    host []
    SMTP error from remote mail server after MAIL FROM:<> SIZE=2390:
    550-Verification failed for <>
    550-Previous (cached) callout verification failure
    550 Invalid sender <>

    Check to see if the following option is enabled under the "Mail" tab in "WHM >> Exim Configuration Manager >> Basic Editor":

    "Sender Verification Callouts"

    If so, try disabling this option to see if the issue persists.

    Thank you.
