Send Mail with Gmail and sSMTP on CentOS 5

sSMTP is an extremely simple, resource conserving, smtp server that will allow your desktop or server to send email. in this article we are going to use sSMTP to send outgoing email through gmail.

1、Install sSMTP.
Unfortunately,ssmtp is not in CentOS 5 yum base repository,so we have to download and install it manually.

#wget ftp://ftp.muug.mb.ca/mirror/fedora/epel/5/x86_64/ssmtp-2.61-11.8.el5.x86_64.rpm
#rpm -Uvh ssmtp-2.61-11.8.el5.x86_64.rpm

2、configure sSMTP
First,backup and empty /etc/ssmtp/ssmtp.conf
#/bin/cp /etc/ssmtp/ssmtp.conf /etc/ssmtp/ssmtp.conf.OLD
#> /etc/ssmtp/ssmtp.conf
#vi /etc/ssmtp/ssmtp.conf
root=sender@gmail.com
mailhub=smtp.gmail.com:587
UseSTARTTLS=YES
RewriteDomain=
Hostname=sender@gmail.com
AuthUser=sender@gmail.com
AuthPass=password
FromLineOverride=YES

add content above,save and quit.

Second,add each account that you want to be able to send mail from by editing, ‘/etc/ssmtp/revaliases’:

#echo ‘root:sender@gmail.com:smtp.gmail.com:587’ >> /etc/ssmtp/revaliases

Please replace sender and password with your Gmail accountname and password.

Third,backup old sendmail
#/bin/mv /usr/sbin/sendmail /usr/sbin/sendmail.OLD
#ln -s /usr/sbin/ssmtp /usr/sbin/sendmail

On my system,sendmail is provided by postfix.

3、Now try sending an email

You can send an email through your favorite email client, like ‘mail’, or type:

ssmtp someemail@email.com

You will then type your message, hit enter and ‘ctrl+d‘

Now that you have a simple outgoing email server setup, you can do all sorts of neat things:
Configure cron jobs to send log reports to your email address
Alert you of all kinds of system changes
Send email alerts when your computer reaches a certain temperature
Send email through PHP, Python, Ruby, and Perl

CentOS5.2、5.3上安装ispCP OMEGA

IspCP Omega 简单介绍:
IspCP 是作为另一款开源虚拟主机管理系统VHCS2的替代产品,采用Apache2+PHP5(fastcgi模式,支持每个虚机独立的php.ini)+MySQL5(提供内置的phpmyadmin)提供 Web 服务(也支持传统的 CGI),FTP 采用 Proftpd(也支持 webftp 功能),邮件是 postfix+courier+squirrermail,和 IspCPH管理平台(PHP 代码,支持管理员、代理商、虚拟主机用户三级用户,相互之间可以自由切换,自由增加子域名、FTP、MySQL、Mail 账号),另外对于每个虚拟主机都有独立的每天完整备份机制(可以用 FTP 下载)。

系统:CentOS5.2,无桌面,安装开发工具,开发库

一、禁用SELinux
# vi /etc/selinux/config

SELINUX=enforcing
修改为
SELINUX=disabled

# vi /etc/sysconfig/network
将HOSTNAME修改为
HOSTNAME=test.test.com

iptables没必要禁了,ispCP安装好后,会生成防火墙规则,并启用iptables

重启系统
# init 6
