Estou configurando uma nova instalação no Ubuntu, estou usando o Zoho como meu provedor de e-mail. Eu ativei a 2FA para a conta de administrador, mas não para a conta noreply, então estou usando a senha do aplicativo 2FA que criei para a senha SMTP.
Estou com o site rodando atrás do NGINX, os e-mails são o único problema que estou enfrentando atualmente.
Aqui está a saída do meu discourse doctor:

Eu também testei o handshake com o OpenSSL e ele está me dando luz verde.
Atualmente, não sei qual é o problema para isso não estar funcionando. Eu tenho o PiHole configurado na frente na rede, embora eu tenha o mesmo e-mail noreply enviando e-mails da minha configuração do VaultWarden.
(Sim, estou buscando mais uma instalação anual (espero) e cheguei mais longe do que qualquer outra tentativa até agora.)
Qualquer ajuda seria muito apreciada,
