Alert Message! received to my mailbox

Hello,

    Every day I received this message that is coming from my own email address, this messages comes around a thousand numbers everyday.

   We have sonic firewall, cisco router, hope to rectify this issue, thanks in advance...



Dear User
Your router has detected and protected you against an attempt to gain access to your network.  This may have been an attempted hacker intrusion, or perhaps just your Internet Service Provider doing routine network maintenance.
Most of these network probes are nothing to be worried about - these types of random probes should NOT be reported, but you may want to report repeated intrusions attempts.  Save this email for comparison with future alert messages.

Spammer is using some kind of E-mail spoofing techniques. If all the emails are coming from same IP you can block the IP to stop the SPAM mails.
