How to make SPF and Forwarders to work with Postfix and Postfix upgrade

Hi, this is little how-to for upgrading Postfix and make this works with the SPF  and forwarders.

It was tested with MariaDB (for MySQL should be installed mysql-devel and mysql-libs I guess):
Upgrade to latest stable 3.1.1 (at the 28.07.2016)

#make config backup#

Code: [Select]

cp -rf /etc/postfix /etc/postfix_backup#Install dependence (will need to build) #

Code: [Select]

yum -y install MariaDB-shared MariaDB-devel cmake # Removing unused parameter #

Code: [Select]

sed -i '/^.*smtpd_bind_address.*$/d' /etc/postfix/master.cf# Get latest Postfix #

Code: [Select]

cd /tmp
wget http://cdn.postfix.johnriley.me/mirrors/postfix-release/official/postfix-3.1.1.tar.gz
tar -xf  postfix-3.1.1.tar.gz
cd postfix-3.1.1# Make makefile with mysql and install #

Code: [Select]

make -f Makefile.init makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_SASL_AUTH -I/usr/include/sasl -DUSE_SSL -I/usr/include/openssl/ -DUSE_CYRUS_SASL -DUSE_TLS' 'AUXLIBS_MYSQL=-L/usr/lib64/mysql/plugin -lmysqlclient -lz -lm -L/usr/lib64/sasl2/ -lsasl2 -lcrypto -L/usr/lib64/openssl/engines/ -lssl
make
sh postfix-install -non-interactive
Make forwarders  works with SPF (SRS)

Code: [Select]

cd /tmp
wget https://github.com/roehling/postsrsd/archive/master.zip
unzip master.zip
cd postsrsd-master/
make
make install
chkconfig postsrsd on # add required params for SPF+SRS #

Code: [Select]

postconf -e "sender_canonical_maps = tcp:127.0.0.1:10001"
postconf -e "sender_canonical_classes = envelope_sender"
postconf -e "recipient_canonical_maps = tcp:127.0.0.1:10002"
postconf -e "recipient_canonical_classes = envelope_recipient"

/etc/init.d/postfix restart
/etc/init.d/postsrsd restart

If something went wrong

Code: [Select]

yum -y reinstall postfix
cp -rf /etc/postfix_backup /etc/postfix
