No meu servidor com Postfix, Dovecot e Postgresql posso receber e-mails com falhas, mas não enviá-los. Via Thunderbird.
Ao tentar enviá-lo, vejo isso nos logs do Postfix:

Note que para receber e-mails eu tenho que usar SSL / TLS nas configurações do meu Thunderbird, enquanto que para enviar quando estou usando SSL / TLS ele não vai se conectar. Quando estou tentando enviar um e-mail e usando o STARTTLS ele pelo menos se conecta.
Você está invocando um serviço de envio com cleanup_service_name=submission-header-cleanup . No entanto, você não tem nenhum serviço chamado submission-header-cleanup configurado.
Remova -o cleanup_service_name=submission-header-cleanup do seu master.cf (o padrão cleanup_service é cleanup e entrará em vigor se você remover essa substituição) ou configure um serviço submission-header-cleanup .
