Sendmail + SPF milter howto

Controllo che sendmail > 8.11 e compilato con il supporto MILTER:

sendmail -d0.1 -bt < /dev/null | grep MILTER

wget http://www.libspf2.org/spf/libspf2-1.2.5.tar.gz
wget http://dfn.dl.sourceforge.net/sourceforge/smfs/smf-spf-2.0.2.tar.gz

tar -zxvf libspf2-1.2.5.tar.gz
cd libspf2-1.2.5
./configure
make && make check
make install
ldconfig

Quando si lancia make check si ottengono questi errori, cmq poi tutto funziona correttamente

cd ..

cd smf-spf-2.0.2
make
make install

vi /etc/mail/smfs/smf-spf.conf

/usr/local/sbin/smf-spf -c /etc/mail/smfs/smf-spf.conf

Add these lines to your Sendmail configuration file (usually sendmail.mc):

define(`confMILTER_MACROS_HELO’, confMILTER_MACROS_HELO`, {verify}’)dnl
INPUT_MAIL_FILTER(`smf-spf’, `S=unix:/var/run/smfs/smf-spf.sock,
T=S:30s;R:1m’)dnl

IMPORTANT: make sure that libmilter is compiled with
BROKEN_PTHREAD_SLEEP defined.
If this symbol is not defined, libmilter will use sleep() in
signal-handler thread,
which may cause various program misbehaviors, including coredumps.
To rebuild Sendmail with this symbol defined, add the following line to your
Sendmail/devtools/Site/site.config.m4:

APPENDDEF(`confENVDEF’, `-DBROKEN_PTHREAD_SLEEP’)

vi /usr/share/sendmail/cf/m4/cf.m4

[La necessità di inserire il parametro sopra-descritto mi è ignota, ma quando ho provato a
aggiungerlo sendmail non partiva]

m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

A questo punto possiamo riavviare sendmail e controllare su /var/log/maillog
se il controllo SPF funziona.
(e a me FUNZIONA 🙂 )
