Re: My domain spoofed sending spam Are the bounced e-mails originating from your own server ? This would indicate that they have guesses/read your password and are relaying. If they are just using your address as a "return" address for the spam they send from their server then you will need to get on an airplane and pay them a very personal visit.
I've had both scenarios occur several times. I also block all e-mail from over seas. Only Domestic and Canadian e-mail even gets to the filters. South of the border is pooled separately. Overseas is completely terminated, which is where 80% of spam comes from.
Not coming from google apps as I can see that from the headers. Changed and strengthened the passwords anyways. Plus did same for the registrar.
also checked all the records etc. too make sure dkim and spf were still set etc.
