[postfix-es] Nuevamente postfix.

Jue Abr 19 15:36:01 CEST 2012

Quiero agradecer a todos lo que han aportado ideas, las cuales he tomado muy
convenientemente. Estoy experimentando utilizando máquinas virtuales antes
de poner en caliente el servidor postfix, tengo 2 mdaemon respondiendo a
Yahoo.es y papasco.co.cu (mi dominio) y entre ellos postfix con los
respectivos DNS y demás.

Al enviar un mensaje desde “papasco.co.cu” a “Yahoo.es” ocurre la siguiente
conversación entre los servidores. Esto también pasa en el sentido inverso.
Es decir  postfix al parecer no está aceptando el mensaje.

La red virtual es:

Postfix -> 192.163.1.2,  200.55.135.13

“Yahoo.es” -> 200.55.135.9

“papasco.co.cu” -> 192.163.1.1

La configuración en curso es:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)

biff = no

append_dot_mydomain = no   

delay_warning_time = 4h  

readme_directory = no

# TLS parameters - comentado para pruebas manuales

#smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem

#smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key

#smtpd_use_tls=yes

#smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache

#smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for

# information on enabling SSL in the smtp client.

myhostname = com-2.papasco.co.cu

mydomain = papasco.co.cu

alias_maps = hash:/etc/aliases

alias_database = hash:/etc/aliases

myorigin = $mydomain

mydestination = com-2.papasco.co.cu, localhost.papasco.co.cu, papasco.co.cu,
localhost, 192.163.1.1

# relayhost = 192.163.1.1

# relay_domain = papasco.co.cu

transport_maps = hash:/etc/postfix/transport

mynetworks = 127.0.0.0/8   192.163.1.0/24   200.55.135.8/29

home_mailbox = Maildir/

message_size_limit = 2097152

mailbox_size_limit = 0

recipient_delimiter = +

inet_interfaces = all

inte_protocols = all

#content_filter = smtp-amavis:[127.0.0.1]:10024

#restrictions

#smtpd_helo_restrictions = reject_invalid_hostname

smtpd_error_sleep_time = 1s

smtpd_soft_error_limit = 60

smtpd_hard_error_limit = 60

#smtpd_recipient_restrictions = permit_mynetworks

#smtpd_sender_restrictions = permit_mynetworks

Y el fichero transport tiene:

papasco.co.cu  smtp:[192.163.1.1]

.papasco.co.cu smtp:[192.163.1.1]

Realmente estoy desconcertado pues en teoría todo lo veo bien puesto, salvo
que faltarían luego los elementos de seguridad.

En espera y agradecido.
