架设RHEL4系统Sendmail邮件服务器(1)(2)

设置邮件别名和邮件群发

修改/etc/aliases文件实现邮件转发和邮件列表：

admin:mike为邮件用户mike设置别名admin

testgroup:mike,john实现群发发给testgroup的邮件发给mike和john以上2个可以分别测试

#newaliases

5.访问控制设置

更改/etc/mail/accesss文件，增加：

[root@localhostnamed]#cat/etc/mail/access

#Checkthe/usr/share/doc/sendmail/README.cffileforadescription

#oftheformatofthisfile.(searchforaccess_dbinthatfile)

#The/usr/share/doc/sendmail/README.cfispartofthesendmail-doc

#package.

#

#bydefaultweallowrelayingfromlocalhost……
