Eu encontrei este problema em outras questões, mas não parece exatamente o mesmo. Eu segui o link para instalar e configurar o Postfix. No final, eu corro o teste e ele retorna o seguinte resultado
250-server1.example.com
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
250 AUTH está faltando. Eu verifiquei o main.cf e smtpd_tls_auth_only = não.
Eu verifiquei o /var/log/mail.log mas ele não contém nenhum erro
