Dovecot Sieve


Versão utilizada: dovecot-sieve-1.1.6

#cd /usr/ports/mail/dovecot-sieve
#make install clean

Configurando o Dovecot na inicialização do sistema:
 
#echo ‘dovecot_enable=”YES”’ >> /etc/rc.conf


Criando certificado SSL/TLS para conexões seguras:
Obs: Estes passos são necessários se pretende usar o SSL, caso contrário pule essa etapa.

#mkdir /etc/ssl/dovecot
#cd /etc/ssl/dovecot
#openssl req -new -x509 -nodes -out cert.pem -keyout key.pem -days 365


Configuração do dovecot.conf

Script Sieve

Crie o diretório /usr/local/etc/dovecot e dentro dele o seguinte script:

#mkdir /usr/local/etc/dovecot
#ee dovecot.sieve
#chown –R vmail /usr/local/etc/dovecot

####################
#
require ["fileinto"];
if header :contains "X-Spam-Level" "********************" {

        stop;
}
elsif
header :contains "X-Spam-Status" "Yes" {
        fileinto "INBOX.Spam";
        stop;
}
#

Agora vamos criar os arquivos de logs.

#touch /var/log/dovecot-lda.log
#touch /var/log/dovecot.log
#chown vmail /var/log/dovecot*




Se tudo ocorreu bem até aqui, verifique se foi criado o caixa de e-mail do usuário em: /var/virtual/

Postfix

Instalando o Postfix


Versão utilizada: postfix-2.4.11

#cd /usr/ports/mail/postfix24
#make config
#make install clean




Durante a instalação o sistema lhe fará duas perguntas, reposta ‘y’ em todas.


Configurando o Postfix

Desabilitando o Sendmail

#echo ‘sendmail_enable="NO"’ >> /etc/rc.conf
#echo ‘sendmail_submit_enable="NO"’ >> /etc/rc.conf
#echo ‘sendmail_outbound_enable="NO"’ >> /etc/rc.conf
#echo ‘sendmail_msp_queue_enable="NO"’ >> /etc/rc.conf

Parando o Sendmail

#/etc/rc.d/sendmail forcestop

Iniciando o Postfix no boot do sistema:

#echo ‘postfix_enable=”YES”’ >> /etc/rc.conf

Crie o arquivo ‘/etc/periodic.conf ‘e adicione as seguintes linhas:

#ee /etc/periodic.conf

daily_clean_hoststat_enable="NO"
daily_status_mail_rejects_enable="NO"
daily_status_include_submit_mailq="NO"
daily_submit_queuerun="NO"


Criando certificados SSL/TLS

#mkdir  /etc/ssl/postfix
#cd /etc/ssl/postfix
#openssl req -new -x509 -nodes -out smtpd.pem -keyout smtpd.pem -days 3650
#chmod 640 /etc/ssl/postfix/smtpd.pem
#chgrp -R postfix /etc/ssl/postfix

Arquivo Master.cf

Descomente a linha “smtps” deixando da seguinte forma:

  -o smtpd_tls_wrappermode=yes
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_client_restrictions=permit_sasl_authenticated,reject


Agora insira a seguinte linha no final do arquivo:

dovecot   unix  -       n       n       -       -       pipe
   flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -d ${user}


Iniciando o Postfix

#mv /etc/aliases /etc/aliases.OFF
#ln –s /usr/local/etc/postfix/aliases /etc/aliases
#postaliases /usr/local/etc/postfix/aliases
#/usr/local/etc/rc.d/postfix start


Testando o envio de mensagem

#telnet mx.neonoc.tld 25

Para gerar essa senha você pode usar o seguinte commando:

#printf '\0Usuario\0Senha' | mmencode

O programa mmencode pode ser encontrado em: “/usr/ports/converters/mmencode”.

Apache

Instalando o Apache


Versão utilizada: httpd-2.2.11

#cd /usr/ports/www/apache22
#make install

As configurações padrões são suficientes para nosso ambiente.

Configurando o Apache para iniciar durante o boot:

#echo ‘apache22_enable=”YES”’ >> /etc/rc.conf

PHP5

Instalando o PHP5

A linguagem PHP é necessária já que nosso Webmail é totalmente escrito em PHP.

Versão utilizada: php-5.2.10

#cd /usr/ports/lang/php5
#make config
#make install clean
