[postfix-es] problemon de rechazo de email en mi servidor. Por vafor AYUDA

[Dionisio Ruiz de Zarate]

Hola sigo con mis problemas que me rechaza correos mi servidor, correos que
provienen de direcciones que antes , hasta que cambie a postfix 2, no me
pasaban.
Alguein comento en esta lista alguna vez la diferencia entre el ehlo y el
helo
puede tener algo que ver con eso?

Jun 23 21:04:53 server postfix/smtpd[15051]: 1A82F1D494: reject: RCPT from
unknown[XXX.XXX.XXX.XXX]: 450 Client host rejected: cannot find your
hostname, [XXX.XXX.XXX.XXX]; from=<remitente en dominio.com>
to=<destinatario.dominio.com> proto=ESMTP helo=<servidor.remitente.com>

rechazando un monton de correos que antes llegaban sin problemas y me esta
desesperando
