Whats the quick way to delete messages.

Is there a quick way to delete all messages posted on a newsgroup, instead of submitting individual url.Currently on google,you have to submit individual url of your message.Is there another method/software that allows you to maybe just enter your email and then it delete all messages from that email address. Or even,another software that allows you to instancely delete the message.

Not sure if you understand what I am saying,cause my English is not that good.

Thank you for your help
