linux下用mailx不启动Sendmail使用其它SMTP发邮件

可能服务器群已有专用邮件服务器不想在每台服务器上开启sendmail服务, 可以使用此方法让其它WEB服务器等调用,方便管理与维护.

1.首先需要一个SMTP邮件服务器 假设已有一台mail.c1gstudio.com邮件服务器

2.在本机的/etc/mail.rc 尾部输入

set [email protected] set smtp=mail.c1gstudio.com set smtp-auth=login set smtp-auth-user=mailuser set smtp-auth-password=mailpassword

3.发送邮件 mail -v -s “Hello ” [email protected] < /etc/hosts 收件人可以是多个人以","分割 -v是显示过程

==================== 2012-4-10更新 以上测试是在centos6.0下运行没有问题,但在centos5.x上无法成功,为此放狗搜了半天无果 某天总算发现了差异,原来centos6上是Heirloom Mailx,在debian上用的多,yum search下没有.

centos5.8

mailx -V 8.1 6/6/93. Type ? for help. “/var/spool/mail/root”: 2 messages 2 new

centos6.0

mailx -V 12.4 7/29/08

找到问题就好办了 heirloom项目网址 http://sourceforge.net/projects/heirloom/ 目前最近版是mailx-12.4 1.安装mailx wget http://sourceforge.net/settings/mirror_choices?projectname=heirloom&filename=heirloom-mailx/12.4/mailx-12.4.tar.bz2 tar jxvf mailx-12.4.tar.bz2 cd mailx-12.4 make make install 出错

test -d /usr/local/bin || mkdir -p /usr/local/bin /usr/ucb/install -c mailx /usr/local/bin/mailx make: /usr/ucb/install: Command not found make: *** [install] Error 127

make install UCBINSTALL=/usr/bin/install

默认安装在 /usr/local/bin/mailx /etc/nail.rc 也可以自定义安装目录

make PREFIX=/opt/mailx SYSCONFDIR=/opt/mailx/etc

2.在本机的/etc/nail.rc 尾部输入 注意是nail.rc不是mail.rc

set [email protected] set smtp=mail.c1gstudio.com set smtp-auth=login set smtp-auth-user=mailuser set smtp-auth-password=mailpassword

3.切换到新mailx mv /bin/mail /bin/mail.OFF ln -s /usr/local/bin/mailx /bin/mail

4.测试 mail -v -s “new mailx ” [email protected] < /etc/hosts

========================== 2013-4-26更新 如出错找不到libiconv.so.2

mailx: error while loading shared libraries: libiconv.so.2: cannot open shar

可以查找下libiconv有无安装,再把lib目录放入/etc/ld.so.conf中 一般在/usr/local/lib/ echo ‘/usr/local/lib/’ >> /etc/ld.so.conf ldconfig -v
