sudo apt-get -u install fetchmail postfix procmail mailutils

Configurar postfix

sudo vi /etc/postfix/main.cf

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


# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = no

# TLS parameters
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 = server.net
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination = server.net, akuma, localhost, localhost.localdomain, localhost
relayhost = smtp.server.net:587
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
#smtp_use_tls = yes
#smtp_sasl_tls_security_options = noanonymous
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 prodigy.net.mx
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
header_checks = pcre:/etc/postfix/header_checks.pcre 

sudo vi /etc/postfix/header_checks.pcre

sudo vi /etc/postfix/sasl_passwd

smtp.server.net:587 user@server.net:password

sudo postmap /etc/postfix/sasl_passwd

 

Cambiar permisos y propietario

 

sudo chown ... ; sudo chmod ... (obvio ¿no?)

 

Reiniciar server

 

sudo /etc/init.d/postfix restart

 

Editar archivo de configuración de fetchmail

 

vi .fetchmailrc

# Configuration created Sun Sep 22 11:35:58 2013 by fetchmailconf 1.57
set postmaster "postmaster"
set bouncemail
set properties ""
poll pop.server.net via "pop.server.net"
with proto POP3 auth password and options no dns
localdomains server.net
user 'user' there with password 'password' is 'user' here options keep fetchall warnings 50000
antispam 571 550 501 554

sudo -u user fetchmail  -v -d 53

Si, la idea es ejecutarlo con un usuario sin privilegios

 

Configurar procmail

 

sudo vi /etc/procmailrc

 

MAILDIR=/var/mail
LOGFILE=$MAILDIR/procmail.log
:0:
#* ^From user@gmail.com
anotheruser

 

Configurar hostname

 

sudo vi /etc/hosts

 

127.0.0.1 server.net
