I am receiving tons of returned emails that I had never sent before. Is there any way to stop it? It seems that my email auto sent to some email address that block my email address.Thanks in advance.

Most likely you receive bounces as a reaction to spam mails, that a spammer is sending with your email address as From: address.

For more informations see e.g. http://en.wikipedia.org/wiki/Backscatter_(e-mail) (as commented by ceejayoz ).

As a workaround you may:

  • use a filter rule in your Mail User Agent (e.g. Thunderbird)
  • use a sieve filter rule, if your Mail Delivery Agent (e.g. Dovecot) support this
  • use procmail to filter out this messages
  • Thank you so much.If I sent an email to [email protected] and it failed, so I get returned email like that :[From]Mail Delivery System.....................This message was created automatically by mail delivery software..........How can I stop it in Cpanel. Thanks (I mean turn it off whenever my email sending unsuccessful)
