Segui esta instrução para configurar um servidor de e-mail no meu VPS:https://www.linuxbabe.com/mail-server/centos-8-iredmail-email-server
Após a instalação ser concluída com sucesso, quando tento o endereço do meu site ( sssss.compor exemplo), ele redireciona automaticamente sssss.com/maile mostra a página de login do e-mail! Portanto, não consigo acessar a primeira página do site.
A seguir estão meus arquivos relacionados em meu VPS.

- If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.
- If you are building a RECURSIVE (caching) DNS server, you need to enable
recursion.
- If your recursive DNS server has a public IP address, you MUST enable access
control to limit queries to your legitimate users. Failing to do so will
cause your server to become part of large scale DNS amplification
attacks. Implementing BCP38 within your network would greatly
reduce such attack surface
