摘要: postfix+dovecot+mysql+postfixadmin(centos6.5)
  • 安装mysql
yum install mysql mysql-devel mysql-server
groupadd -r -g 65501 vacation
useradd -r -u 65501 -g vacation -d /var/spool/vacation -s /sbin/nologin vacation
mkdir /var/spool/vacation
  • vmail账号设置
groupadd -g 5000 vmail
useradd -g vmail -u 5000 vmail -d /data/vmail -m
  • 编译安装postfix-2.8.0(SSL+MYSQL支持)
make -f Makefile.init makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_SSL -I/usr/include/openssl/ -DUSE_TLS'   'AUXLIBS=-L/usr/lib/mysql -lmysqlclient -lz -lm -lssl -lcrypto'
