Problemas de autenticação TLS com Outlook + Dovecot + Postfix + CentOS 8

Problemas de autenticação TLS com Outlook + Dovecot + Postfix + CentOS 8

Espero que você esteja bem! Sou novo em VPS não gerenciado e estou rodando um servidor Contabo com CentOS 8 e AaPanel meu problema é com a conexão SMTP com Outlook, meu servidor só está aceitando conexões SMPT com STARTTLS ou sem nenhum tipo de criptografia, mas gostaria para aceitar conexões com TLS, estou usando Postfix e Dovecot para gerenciamento de email, estou anexando meus arquivos de configuração, desde já agradeço a todos.

NOTA: POP3 e IMAP estão funcionando perfeitamente; SMTP também, mas na porta 587 sem criptografia; Tive que remover algumas linhas comentadas para poder postar a pergunta aqui.
