postfix relay mail from localhost

Question

Estou tentando configurar o postfix com o domínio virtual para o dovecot lmtp.

A configuração deve:

• aceitar retransmissão somente de usuários autenticados ou e-mails provenientes de localhost
• verifique se o usuário sasl possui o e-mail da entrada (ldap)
• aceita correio para domínio local somente por meio da verificação de endereço dinâmico em combinação com o dovecot lmtp

Tudo funciona, exceto retransmissão de email proveniente de localhost, embora eu tenha definido allow_mynetworks.

Com o telnet, recebo a resposta:

453 4.7.1 : Sender address rejected: not logged in
