Looking for mail-bomb-server



I’m looking for a mail-bomb-server. I found +/- 1 year ago a SMTP-server which allowed me to send anonymous mails, but now the server doesn’t work anymore. (it’s probably sercured )
I need it to mail a sucker who mails my brother, and that sucker recently found out what ctrl+c and ctrl+v do, so he sends all sorts of shit mails to my brother!

So if you know a anonymous SMTP-server, please post it here!
