[Postfix-es] No llegan correos a hotmail ni wanadoo

[Postmaster]

Hola buenas, tengo un problemas con algunos proveedores.
Envio correos pero no llegan a sus destinatarios, normalmente me suele pasar
con, wanadoo y con hotmail. A ellos nunca les llega

Tengo  la version de postfix = 2.0.18
Se ha instalado mediante rpm en una fedora core 2
Para poder enviar correos tienes que autentificarte (mi servidor requiere
autentificacion) SASL.
Todo esta funcionando conjuntamente con un VHCS 2.4

Cuando envio el correo esto es lo que me sale en el maillog

postfix/qmgr[14224]: EEF2254C006: from=<cuenta en iseval.com>, size=515,
nrcpt=1 (queue active)
amavis[27048]: (27048-08) FWD via SMTP: <cuenta en iseval.com> ->
<cuenta en hotmail.com>, 250 2.6.0 Ok, id=27048-08, from
MTA([127.0.0.1]:10025): 250 Ok: queued as D01A654C00C
amavis[27048]: (27048-08) Passed CLEAN, [84.126.194.210] <cuenta en iseval.com>
-> <cuenta en hotmail.com>, Message-ID: <462C95A6.7080907 en iseval.com>, mail_id:
GYp4+GAjxJaq, Hits: -93.689, 436 ms

Si miro el id del correo con el grep en maillog veo esto

postfix/smtp[27603]: D01A654C00C:to=<cuenta en hotmail.com>,
relay=mx4.hotmail.com[65.54.245.104], delay=2, status=sent (250 
<462C95A6.7080907 en iseval.com> Queued mail for delivery)

Pone que status sent, pero veo que pone queued mail for delivery. sin
embargo no está el correo en mis colas.. asi que he de pensar que lo ha
enviado, pero porque no llega a hotmail?
