Mailbox is full with undeliverable mails

[seby]

My mail box is always getting full and getting lot of undeliverable mails in my default account, eventhough I didnt send any mails. Is there a way I could bounce back all these mails ?

You are getting lot of undeliverable mails and if you didnt sent it, you might be the victim of mail spoofing attack or spammers utilized your domain in their mail return 'To' setting.

We recommend to disable the Catch All email account to bounce back all those undeliverable failures. To disable the Catch All address:

Step 1.Login to your web control panel http://domain.com/cpanel
Step 2.Click on Default Address (Under the Mail tab)
Step 3.Check Discard with error to sender (at SMTP time)
Step 4.Click Change and you will no longer receive any such mails.

Hope this helps.

We have the same problem with our doimain. I have received hundreds of these undeliverable messages and I am worried about our account being closed down for abuse.

Ugh.....

Any help would be greatly appreciated.

Thanks,

Did you disable to catch all/default address in your cPanel?

If you are sure that it is a spoofing attack then it may not be possible to prevent it completely since it is being done by a third party probably using a compromised server. It can be limited to a certain extent by adding SPF records. You can open a Support ticket to have SPF record added to your domain's DNS.
