Problema con envio de mail via PHP mail()

[n0dix99]

Gracias por la respuesta.
Pero en vista que no podia instalar el servidor con el postfix, intente con el qmail.

Instale qmail e hice el cambio en el php.ini para que utilizace el qmail-inject. Cuando intento enviar un mensaje me sale de error:
Sorry,_I_wasn't_able_to_establish_an_SMTP_connecti on._(#4.4.1)/

He hecho un telnet localhost 25 , y no he tenido problemas.

Tal vez el problema que tengo es el mismo que para postfix. He buscado configurar un relayhost para qmail. He configurado el /etc/tcp.smtp :
127.:allow,RELAYCLIENT="".

Y mi /etc/host/ es:
127.0.0.1 localhost
127.0.1.1 n0dix

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Mi "/var/qmail/bin/qmail-showctl" es:
