升级postfix至postfix-2.10.3

已有sasl2和mysql情况下

chkconfig sendmail off
/etc/rc.d/init.d/sendmail stop

关闭原有的sendmail：

mv /usr/sbin/sendmail /usr/sbin/sendmail.OFF
mv /usr/bin/newaliases /usr/bin/newaliases.OFF
mv /usr/bin/mailq /usr/bin/mailq.OFF
chmod 755 /usr/sbin/sendmail.OFF /usr/bin/newaliases.OFF /usr/bin/mailq.OFF

文件解锁,可省略

chattr -i /etc/passwd /etc/shadow /etc/group /etc/gshadow /etc/services

添加用户和组,已有可省略

groupadd -g 2525 postfix
useradd -g postfix -u 2525 -s /sbin/nologin -M postfix
groupadd -g 2526 postdrop
useradd -g postdrop -u 2526 -s /sbin/nologin -M postdrop

sasl升级安装

ftp://ftp.cyrusimap.org/cyrus-sasl/cyrus-sasl-2.1.26.tar.gz
tar zxvf cyrus-sasl-2.1.26.tar.gz
cd cyrus-sasl-2.1.26
./configure –prefix=/usr/local/sasl2 –disable-gssapi –disable-anon –disable-sample –disable-digest –enable-plain –enable-login –enable-sql
make
make install

移除旧版

mv /usr/lib/libsasl2.a /usr/lib/libsasl2.a.OFF
mv /usr/lib/libsasl2.la /usr/lib/libsasl2.la.OFF
mv /usr/lib/libsasl2.so.2.0.19 /usr/lib/libsasl2.so.2.0.19.OFF
mv /usr/lib/sasl2 /usr/lib/sasl2.OFF
rm /usr/lib/libsasl2.so
rm /usr/lib/libsasl2.so.2

ln -sv /usr/local/sasl2/lib/* /usr/lib
postfix 2.3以后的版本会分别在/usr/local/lib和/usr/local/include中搜索sasl库文件及头文件，故还须将其链接至此目录中：
ln -sv /usr/local/sasl2/lib/* /usr/local/lib
ln -sv /usr/local/sasl2/include/sasl/* /usr/local/include

postfix升级安装

wget ftp://ftp.reverse.net/pub/postfix/official/postfix-2.10.3.tar.gz
tar xfv postfix-2.10.3.tar.gz
cd postfix-2.10.3
make tidy
make -f Makefile.init makefiles ‘CCARGS=-DUSE_SASL_AUTH -I/usr/local/sasl2’ ‘AUXLIBS=-L/usr/local/sasl2 -lsasl2 ‘
make && make install
