Estou com um problema ao obter meu volume baixo de mensagens de e-mail legítimas por meio dos filtros de SPAM do Gmail e do Yahoo.
Eu segui o guia do Gmail aqui: link
Eu também confirmei com o mail-tester que meu SPF, DKIM, etc estão configurados corretamente. Testes adicionais com o MXToolbox confirmam.

Eu suspeito que a entrada de cabeçalho:

by otto.ruestow.me (Postfix) with ESMTPSA id 489E310EBF;

pode ser o problema. O que devo resolver em seguida para permitir que minhas mensagens sejam entregues corretamente?
** ATUALIZAÇÃO **
Eu reconfigurei meu cliente de e-mail para enviar o endereço de e-mail na ID da mensagem e para definir o domínio na entrada de cabeçalho "Recebido: de", mas essas mensagens ainda estão marcadas como SPAM. Estou perplexo.
