Postfix com Courier (Maildir)

• courier-authdaemon
• courier-authlib
• courier-base
• courier-imap
• courier-pop

root@debian:~# aptitude install <pacotes>

Criar diretórios para a administração baseada na Web ? <Não>

Aqui precisamos configurar o Postfix para aceitar o modelo Maildir.

root@debian:~# vi /etc/postfix/main.cf

[...]
home_mailbox = Maildir/
#mail_spool_directory = /var/mail

mailbox_command = /usr/bin/procmail -a "$EXTENSION" DEFAULT=$HOME/Maildir/ MAILDIR=$HOME/Maildir/
[...]

Precisamos ajustar a PAM para autenticar no sistema. Primeiro renomeamos os arquivos originais.

root@debian:~# mv /etc/pam.d/pop3 /etc/pam.d/pop3.bkp
root@debian:~# mv /etc/pam.d/imap /etc/pam.d/imap.bkp

Em seguida, crie os arquivos a seguir com os respectivos conteúdos.

root@debian:~# vi /etc/pam.d/pop3

@include common-auth
@include common-account
@include common-password
@include common-session

root@debian:~# vi /etc/pam.d/imap

@include common-auth
@include common-account
@include common-password
@include common-session

root@debian:~# vi /etc/pam.d/smtp

@include common-auth
@include common-account
@include common-password
@include common-session

Por fim, reinicie os serviços.

root@debian:~# /etc/init.d/courier-authdaemon stop
root@debian:~# /etc/init.d/courier-authdaemon start

root@debian:~# /etc/init.d/courier-pop stop
root@debian:~# /etc/init.d/courier-pop start

root@debian:~# /etc/init.d/courier-imap stop
root@debian:~# /etc/init.d/courier-imap start

Precisamos também criar o Maildir (Caixa Postal) do usuário.

root@debian:~# maildirmake ~usuario/Maildir
root@debian:~# maildirmake ~usuario/Maildir/.Enviadas
root@debian:~# maildirmake ~usuario/Maildir/.Rascunho
root@debian:~# maildirmake ~usuario/Maildir/.Lixeira
root@debian:~# maildirmake ~usuario/Maildir/.Spam
root@debian:~# maildirmake -q 104857600S ~usuario/Maildir
root@debian:~# chown -R usuario.grupo ~usuario

root@debian:~# telnet localhost 110
