[Postfix-es] 504 <loclahost>: Helo command rejected: need fully-qualified hostname

[José María Martín-Nieto Carabaias]

Saludos a la lista.

	En /var/log/mail.log aparecen las siguientes líneas:

postfix/smtpd[3505]: starting TLS engine
postfix/smtpd[3505]: connect from unknown[10.19.2.13]
postfix/smtpd[3505]: NOQUEUE: reject: RCPT from unknown[10.19.2.13]: 504
<loclahost>: Helo command rejected: need fully-qualified hostname;
from=<kas> to=<kas> proto=ESMTP helo=<loclahost>

	Esto es tras haberme conectado por telnet. Lo mismo ocurre si lo hago
mediante Outlook, sólo que donde antes ponía <loclahost>, aparece el nombre
de la maquina desde donde lo intento. Como puedo resolverlo?, he pensado en
eliminar la restricción, pero me parecía cutre. Puede deberse a una mala
configuración de DNS, aunque son dominios diferentes?

	Por si sirve de ayuda: mail_version = 2.1.5, y la salida de postconf -n:
