[postfix-es] Ayuda con COnexion lenta de postfix

[Yunier]

Hola amigos: Tengo un servidor postfix en ubuntu 9.10, el tema es q cuando
doy telnet desde cualquier pc en la RED, (alta velocidad) al puerto 25
(telnet postfixhost 25) me responde con 30 o 40 segundos de atraso la
respuesta 220.

internamente no tengo firewall, lo  mas extraño es q desde el propio
servidor posftix doy un telnet 127.0.0.1 25 y me responde al momento.

En los logs no veo nada sobre el tema.

DATOS

version postfix 2.6.5

lo instale desde el repositorio de ubuntu. deb

Software adicionales que estoy usando SASL, TLS, MySQL SPAMASSINE,
AMAVIS-NEW, POSTGREY, CLAMAV
