linuxmail account full of undeliverable notifications

I have an account on which i don’t use it too much. I hadn’t login for more that 2 months.

The account was over quota from the Undeliverable (or returned ) mails new viruses send using my email as the from address, or spams that spammers send using the same method

It will take me some time to clear it up. It is more than 350 mail messages 🙂
