he encontrado esto pero quisiera implementar esto de la siguiente forma

1-usuarios pueda mandar tanto local como externamente e igual manera recivir

2-usuarios solo puedan mandar local , recibir local y externamente

por ejemplo:

denisenrique@midominio.com      local , externamente(envia local y exter ,ademas recibe local y externamente)

christian@midominio.com             local(envia local, ademas recibe local y externamente)

 

agradeceria mucho sus respuestas

 

 

Postfix smtpd_restriction_classes for Dummies - Part IIOK, another example for those of you who still don't get it:

Question:

I have a customer who wants a setup where all his users can send mail to each other internally, all users will be able to receive email from the outside but only some of the users will be able to send mail outside.

Answer:

In main.cf, use:

mynetworks = 127.0.0.0/8 smtpd_restriction_classes = may_use_external_mail, only_internal_mail smtpd_recipient_restrictions = permit_mynetworks reject_unauth_destination check_client_access hash:/etc/postfix/policy_by_machines # Alternative: # check_sender_access hash:/etc/postfix/policy_by_senders ... your favourite anti spam stuff here ... permit may_use_external_mail = permit # allow ANY mail only_internal_mail = check_recipient_access hash:/etc/postfix/allowed_recipients # allow internal mail reject

in /etc/postfix/policy_by_machines:

workstation1.internal.domain may_use_external_mail workstation2.internal.domain only_internal_mail

or for the alternative, use in /etc/postfix/policy_by_senders:

user1@your.domain may_use_external_mail user2@your.domain only_internal_mail

in /etc/postfix/allowed_recipients:

your.domain OK

Restricciones de acceso(main.cf):

smtpd_restriction_classes = mail_externo, solo_local# enviar sólo al dominio local
solo_local = check_recipient_access hash:/etc/postfix/dominios_locales, reject
mail_externo = permit

#en local_domains, los dominios internos para los usuarios locales

La verdad, esto es muy sencillo, sólo tienes que llamar a tu imaginación para poder hacer la configuración, te acomodé estas líneas de la mía, yo trabajo con Mysql+postfix, y en eso lo puedes mejorar aún más. Espero te sirva y ya me voy porque en mi empresa tengo unos servers que están por morir....

Suerte.

Saludos.

smtpd_restriction_classes = mail_externo, solo_local# enviar sólo al dominio local

estos usuarios que  pueden mandar correo local ,pueden recibir correo externo?

si la repuesta es no que puedo hacer que acepte correo externo?

 

Gracias

disculpen algo extenso , estoy dudoso si en realidad lo que hice esta bien ,

lo que hice funciona de la siguiente manera, tengo 2 usuarios de ejemplo

denis@midominio.com inter(envia y recibe correo interno y ext)
christian@midominio.com local(envia correo local, recibe correo ext)

cree un archivo en /etc/postfix/usuarios
denis@midominio.com inter
christian@midominio local

ademas otro archivo en /etc/postfix/interno
midominio.com OK

y claro luego aplique postmap usuarios y postmap interno

en ultima hora pues el correo christian que es local permitio enviar un correo ha hotmail, y nodeberia de ser asi , que hice me malo, sera mi configuracion en postfix?

gracias por todas las ayudas.
