[Postfix-es] Debian+Postfix+SPF

[Alejandro Cabrera Obed]

Dear all,

Tengo un mail server con Debian Etch + Postfix 2.3.8 + libmail-spf-query-perl 1.999.

Para hacer andar el mecanismno SPF hice lo siguiente:

#apt-get install libmail.sqp-query-perl

#cp libmail-spf-query-perl /usr/local/sbin/smptd-policy.perl

#chown nobody:root usr/local/sbin/smptd-policy.perl

#chmod 755 usr/local/sbin/smptd-policy.perl

En /etc/postfix/master.cf agregue:

policy  unix  -       n       n       -       -       spawn
      user=nobody argv=/usr/bin/perl /usr/libexec/postfix/smtpd-policy.pl

En /etc/postfix/main.cf tengo:

smtpd_recipient_restrictions =
        check_recipient_access hash:/etc/postfix/access
        permit_mynetworks
        reject_unknown_sender_domain
        reject_unauth_destination
        check_policy_service unix:private/policy

En /etc/spamassassin/init.pre descomente:

# SPF - perform SPF verification.
loadplugin Mail::SpamAssassin::Plugin::SPF

Luego de reiniciar el servicio Postfix tengo los siguiente en mail.log:

Jan  8 10:34:00 mail postfix/spawn[10433]: warning: command /usr/bin/perl exit status 2
Jan  8 10:34:00 mail postfix/smtpd[10431]: warning: premature end-of-input on private/policy while reading input attribute name
Jan  8 10:34:01 mail postfix/spawn[10433]: warning: command /usr/bin/perl exit status 2
Jan  8 10:34:01 mail postfix/smtpd[10431]: warning: premature end-of-input on private/policy while reading input attribute name
Jan  8 10:34:01 mail postfix/smtpd[10431]: warning: problem talking to server private/policy: Connection reset by peer

Como se configura SPF adecuadamente en Postfix ??? Alguien lo ha hecho andar con libmail-spf-query-perl ???

Gracias

Alejandro
