企业邮件系统-Postfix安装使用

Postfix是目前流行的一套邮件传输代理软件（MTA），其作者Wietst Venema最初开发这套软件时就对总体设计、扩展能力、可用性及系统安全等方面进行了充分的考虑。由于Postfix在稳定、效率、安全和可用性上的优势，使得很多大型的邮件服务提供商都从原有的MTA软件向Postfix过度，而新仅诞生的邮件产品也大多采用了Postfix。网易、Tom和新浪都将原有的Qmail更换为Postfix，可见Postfix在大规模邮件系统中有比较普遍的应用，当然，Postfix也完全适用设计中小型的邮件系统，因为Postfix在保证了效率、安全、扩展等方面优势的同时，还具有配置简单的特点。[比较老的数据了]

 

碎语：

又开始捣腾我比较喜欢的邮件系统了，本文为后面的邮件系统做铺垫，后面在来关联文章树，本文LNMP环境基于LNMP一键安装，请自行通过博客搜索功能搜索该关键词

 

基于CentOS6.5，环境minimal，卸载postfix

[root@ipython ~]# service postfix stop Shutting down postfix: [ OK ] [root@ipython ~]# rpm -e --nodeps postfix

 

安装Postfix

[root@ipython ~]# yum install db4-devel [root@ipython ~]# tar zxf postfix-2.12-20140801.tar.gz [root@ipython ~]# cd postfix-2.12-20140801 ####直接编译Makefiles#### ###AUX = 扩展功能[就这理解着吧] -lz = 压缩工具 -lm = 编码支持 #### ####lssl = openssl加密支持 lcrypto = crypto库 #### ###如果你参考了本文，请不要看别的文章，并且最好使用我打包好的免安装LNMP或一键安装LNMP做完一次完整的测试后，再尝试跟着你自己的感觉走哦### ###当然，如果你仍采用了自己的思路并参考了本文，那么请修改下面的依赖文件的路径，欢迎提问### [root@ipython postfix-2.12-20140801]# make makefiles CCARGS='-DHAS_MYSQL -I/software/mysql/include/mysql -DUSE_SASL_AUTH -DDEF_SERVER_SASL_TYPE=\"dovecot\" -DUSE_TLS -I/software/openssl/include' AUXLIBS='-L/software/mysql/lib/mysql/ -lmysqlclient -lz -lm -L/software/openssl/lib/ -lssl -lcrypto' [root@ipython postfix-2.12-20140801]# make ###给权限哦### [root@ipython postfix-2.12-20140801]# chmod a+x postfix-install [root@ipython postfix-2.12-20140801]# ./postfix-install -non-interactive install_root=/ tempdir=/tmp config_directory=/etc/postfix command_directory=/usr/sbin/ daemon_directory=/software/postfix data_directory=/var/lib/postfix html_directory=no mail_owner=postfix mailq_path=/usr/bin/mailq manpage_directory=/usr/local/man newaliases_path=/usr/bin/newaliases queue_directory=/var/spool/postfix readme_directory=no sendmail_path=/usr/sbin/sendmail setgia_group=postdrop

 

Postfix自动启动

###postfix 启动脚本可以参考 blfs-bootscripts 包，依赖redhat-lsb，由于太大，这里放弃### ---手动建立--- ---------------------/etc/init.d/postfix--------------------------- #!/bin/bash # # postfix Postfix Mail Transfer Agent # # chkconfig: 2345 80 30 # description: Postfix is a Mail Transport Agent, which is the program \ # that moves mail from one machine to another. # processname: master # pidfile: /var/spool/postfix/pid/master.pid # config: /etc/postfix/main.cf # config: /etc/postfix/master.cf # # Based on startup script from Simon J Mudd <[email protected]> # 25/02/99: Mostly s/sendmail/postfix/g by John A.
