Hello. When I send an e-mail from, for example Gmail o Yahoo, if remote mailbox don't exists, the servers sends a notification to the sender. But from Cpanel e-mail accounts, sending an e-mail to a unavailable remote box, don't returns nothing to the sender. Only shows a notification on WHM. And, of course, the most senders don't have access to WHM...

Any solution? Thanks.

Hello :)

If an email account on your cPanel server sends an email to a remote address that does not exist, it should receive a bounceback from the remote mail server if the remote mail server has configured emails to non-existent email accounts to bounce. Have you checked /var/log/exim_mainlog to see if the bounces were delivered?

Thank you.

That shows the bounce was successfully sent to the original sender.

Thank you.
