A spammer is flooding the net with e-mails supposedly being sent by one of my valid business e-mails. I have received hundreds of bounces today for undeliverable messages. How would I track down the perpetrator? Any ideas? I have the e-mail address associated with far too many services/accounts to start trying to change account details and then deactivate the address.

You can't

you may be able to find the originating ip address and report it, but apart from that there could be nothing else

yes you can!

adding SPF records should help, it stands for sender policy framework and should stop people forging the from address.

Actually, my webhost agrees: http://www.openspf.org/Introduction

If this keeps up, I will likely roll up my sleeves and learn how this works. Thanks!

I've yet to see any proof of SPF records actually doing anything, as they can be spoofed as well

Does anyone else have experience with SPF and its usefulness?

I have tried everything - nothing seems to prevent anyone spoofing anyones email, or mobile number for that matter
