>What can I do about this?
>
>I have my own domain name "Wonderley.com." One thing I have always loved is that I could logon to a site that required an email address with a unique email name just for email from them. Something like businessname@wonderley.com.
>
>If for some reason I started getting SPAM to that email address I know that someone with their company sold my email address. It happens, but not too often. Best_Buy was the most surprising. Once it happens, I email the company and so far none of them seem to care. I also add a filter to block emails from then on.
>
>However, I now have someone sending out a lot of spam claiming to be from the Wonderley.com domain. The address at Wonderley.com is most of the time just random gibberish. Bust recently there have been a lot from BatWonderleyMan@wonderley.com.
>
>I don't know how many went out, but yesterday, in just a few hours, I had over 600 replies from "out of office" agents and "You message has been blocked" type emails.
>
>I can add filters in order to clean up what I see, but I don't want companies adding filter that do something like "filter out anything from Wonderley.com" and I just don't like the idea of a spammer using me like that.
>
>I have no idea how to stop this from happening. Any ideas would be appreciated.
>
>Thanks for any help or even reading this far to see of you could help

You might take the full header of the email you have received, locate the source and send a complaint to abuse at their email.

Note also that many do not know what you entered as an email at a specific site. Many would simply guess and try all kinds of variations until they find emails that they send which are not bouncing.
