Possible Email Spamming
For the past couple of days I am receiving lots of undelivered emails on one of my domain which are like this
Undelivered Email : joe@mydomainname.com
Undelivered Email : Marry@mydomainname.com
Undelivered Email : tom@mydomainname.com
Undelivered Email : harry@mydomainname.com
I have not sent these emails, and I am not sure why they are being returned to me. When I check my server logs, these are not shown, as the relaying is not allowed. I have catchall enabled on this domain name. Any help to minimize/eliminate such emails will be appreciated. I do not want my host to cancel my server, on account of sending such emails.
Regards,
