如何在Linux下安装Sendmail服务器(1)

Sendmail现在是最流行的邮件服务器，那我们来看看如何在Linux下安装Sendmail服务器。

1、从www.sendmail.org下载最新的版本(这个snedmail倒是有必要升级为最新的版本，因为它的升级主要是安全漏洞问题)。这里说明的是用的sendmail-8.12.2.tar.gz

2、cd /usr/local/src/

3、把文件下载到：/usr/local/src中

4、tar zxvf sendmail-8.12.2.tar.gz

5、cd /usr/local/src/sendmail-8.12.2

6、chmod go-w / /etc /etc/mail /usr /var /var/spool /var/spool/mqueue

7、chown root / /etc /etc/mail /usr /var /var/spool /var/spool/mqueue

8、cd /usr/local/src/sendmail-8.12.2/sendmail

9、sh Build

10、cd /usr/local/src/sendmail-8.12.2/cf/cf

11、建立文件sendmail.mc内容如下，你可根据需要修改相应部分。

dnl This is the macro config file used to generate the /etc/sendmail.cf

dnl file. If you modify thei file you will have to regenerate the

dnl /etc/sendmail.cf by running this macro config through the m4

dnl preprocessor:

dnl m4 /etc/sendmail.mc > /etc/sendmail.cf

dnl You will need to have the Sendmail-cf pacage installed for this to work.
