fiz aqui e apresetou o seguinte

tcp4       0      0  127.0.0.1.25           *.*                    LISTEN

nmap -p 25 127.0.0.1

PORT   STATE SERVICE
25/tcp open  smtp

nmap -p 25 200.XXX.XXX.XXX

PORT   STATE    SERVICE
25/tcp filtered smtp

Realmente a porta esta ativa, porem A minha duvida se é realmente necessario o 
sendmail ativo para
o envio destes e-mail administrativo atraves do comando mail.

Obrigada
