PowerMTA-Service CentOS 64位系统
手动安装PowerMTA4.0以及4.5r11-5.0r1
装完后无法启动
然后输入：pmtad --debug
查看错误信息如下：

这个问题其实很简单！
河马大叔提到配置问题以及内存小于4G，其实1G内存照样可以，
所以，河马大叔说的不对
当然也不是许可证的问题！
错误原因: 源的问题，破解版必须使用破解源，如果用在线yum install 的安装方式 则会以失败告终！
大多数人都是用这个命令安装的！【错误】 yum install /var/tmp/powermta.rpm
破解版pmta不是这样安装的！
解决办法：
先卸载掉：php* httpd* mysql* bind* postfix dovecot logwatch selinux-policy
卸载命令：yum remove php* httpd* mysql* bind* postfix dovecot logwatch selinux-policy -y
安装下Powermta所必须的依赖包！
yum install bc vim-enhanced mysql-server httpd mod_ssl MySQL-python php gd php-gd php-xml php-mbstring php-mysql php-imap postfix cyrus-sasl cyrus-sasl-devel cyrus-sasl-gssapi cyrus-sasl-md5 cyrus-sasl-plain dovecot zip unzip openssl-devel make gcc sendmail-devel python-setuptools python-devel htop mlocate subversion nmap telnet yum-utils bind bind-chroot bind-libs bind-utils caching-nameserver opendkim vixie-cron ftp screen ntp ntpdate rdate wput squirrelmail squid -y
不然会提示以下错误
error: Failed dependencies:
/usr/bin/perl is needed by PowerMTA-4.5r1-201509101911.x86_64

然后就可以正式安装PowerMTA-4.01.rpm 了
你也可以手动替换！我用的是我自己做的包
rpm -ivh /root/Crack/PowerMTA-4.5.rpm
停止pmta以及pmtahttp，不然替换会出错
service pmta stop
service pmtahttp stop
然后给与权限：chown pmta:pmta /etc/pmta/ -R
pmtad文件 覆盖"/usr/sbin/pmtad
pmtahttp文件 覆盖"/usr/sbin/pmtahttp
license授权文件覆盖"/etc/pmta/license
cp -i license /etc/pmta/
y
cp -i pmtad /usr/sbin/
y
cp -i pmtahttpd /usr/sbin/
y
重启PMTA，注意，默认的配置文件需要自己配置一下，
[root@localhost ~]# service pmta restart
Stopping PowerMTA: [确定 ]
Starting PowerMTA: [确定 ]
[root@localhost ~]# service pmtahttp restart
OK。到此结束，问题完美解决！大家有什么不懂的可以来问我哦！
