Postfix com Dovecot desconecta após STARTTLS na porta 25

1

Estou tendo muitos problemas para configurar o Postfix para fazer STARTTLS. Parece que eu consegui enviar emails com êxito usando o Thunderbird. No entanto, parece que o SMTP do Postman para Wordpress não funciona com o STARTTLS e o PLAIN AUTH.

configurei meu firewall para abrir apenas a porta 25:

    ACCEPT     all  --  anywhere             anywhere             state RELATED,ESTABLISHED
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:ssh
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:http
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:https
ACCEPT     icmp --  anywhere             anywhere             icmp echo-request state NEW,RELATED,ESTABLISHED
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:smtp
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:memcache
REJECT     tcp  --  anywhere             anywhere             tcp dpts:netbios-ns:netbios-ssn reject-with icmp-port-unreachable

Eu poderia abrir a porta 25 com -starttls bem.

Eu tenho lido e lido e não vou a lugar nenhum. Por favor me ajude a encontrar o meu erro. Sua ajuda é muito apreciada.
