postfix mining namespaces

Prezados,

estou com um grande problema no meu servidor de correio. O servidor foi bloqueado pelo outlook.com, yahoo e aol (talvez outros) porque está mandando emails para endereços diversos desses provedores. Não sei como isso se chama em português, mas a achei informações sobre "mining namespaces".


Possuo um servidor Debian com Postfix e Cyrus, rodando também um apache/php para a ferramenta Expresso Livre.
Meu servidor só permite o envio a partir dele mesmo ou de alguns poucos servidores na mesma rede e está bem restrito nesse critério, tanto que os sites que testam quanto a relay, dizem que meu servidor está fechado para relay.

Acho que podem estar usando uma falha do apache/php para mandar esses emails. Alguma sugestão para descobrir de onde está vindo a falha?

Agradeço desde já,
Carlos Alberto

PS: A propósito, eis uma parte do log do postfix (substituí o nome do servidor por "meu_srv"):
