Hi. This is the qmail-send program at hm398.locaweb.com.br.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

Sera que meu ip da internet ta na lista nesse tal de spamcop??
Tem que ir la no site do spamcop e liberar?

O engraçado é que se mando pro meu mail particular do hotmail e yahoo chega normalmente....
