Already tried. Bot is still sending strong...

It may not be sending though your account, it maybe forging the from header to make mail look like it was sent by you. Check the email headers of the bounce back mails to see if its actually coming from your server. Also keep in mind that if you do stop the bot you'll most likely keep getting backscatter for a while (days) while mail queue clear out.
