Postfix Mail sendo redirecionado para caixa de entrada privada

Sou relativamente novo no Linux, configurando servidores e principalmente lidando com coisas relacionadas a correio. Comprei um novo domínio e aluguei um VPS, que agora hospeda meu site. Preciso de um ambiente mais aberto para meu projeto web, incluindo a geração automática de endereços de e-mail e a leitura de suas caixas de entrada. É por isso que não consegui usar um pacote normal de hospedagem na web.

Resumindo, sou um iniciante e tive um problema ao configurar o postfix, para o qual não consegui encontrar nenhuma solução online. Cheguei ao ponto em que o servidor web é executado com um certificado válido e o mesmo nome de domínio do meu servidor web. Significa que solicitar https://example.com funciona e enviar mensagens [email protegido] funciona.

Parece bom até agora. Meu problema é que qualquer e-mail enviado para qualquer caixa de entrada é automaticamente redirecionado para meu e-mail particular.

Isso significa o seguinte, digamos que alguém envie um email para [email protected] . Em vez de poder visualizar este e-mail usando s-nail, o e-mail é encaminhado para meu endereço privado.

[e-mail protegido] -> [e-mail protegido] -> ??? -> [e-mail protegido]

Provavelmente cometi um erro ao configurar o postfix. Achei que poderia ter definido o valor errado para "Destinatário de correio raiz e postmaster".

Por esse motivo tentei reconfigurar o postfix usando sudo dpkg-reconfigure postfixe reiniciar o serviço usando sudo systemctl restart postfix. Isso não mudou nada.
