RHEL4Sendmail邮件服务器的架设转载：linux.chinaitlab/server/_2.html 这次我们来学习Linux系统中的Sendmail服务器的配置。（邮件服务器的IP192.168.1.2主机域名为mail.ltest） 前提：首先我们 把DNS服务器安装OK能够解析，不明白的看linux.chinaitlab/server/.html 1.首先安装Sendmail所需软件 # rpm -q sendmail m4 sendmail-8.13.1-2 m4-1.4.1-16 已经默认安装了，还需挂载第4张光盘，安装与sendmail相关的软件 # rpm -ivh sendmail-* warning: sendmail-cf-8.13.1-2.i386.rpm: V3 DSA signature: NOKEY,key ID db42a60e Preparing…… ########################################### 1:sendmail-doc ########################################### [33%] 2:sendmail-cf ########################################### [67%] 3:sendmail-devel########################################### 2.修改/etc/mail/local-hosts-name文件。 增加本地域和主机的FQDN，记住只是本地主机的FQDN和域名FQDN，不要添加其他域的，否则向外域发送邮件的时候会出现userunknown的错误： # cat /etc/mail/local-host-names # local-host-names - include all aliases for your machinehere. ltest 3.更改/etc/mail/sendmail.mc文件，修改下列地方： DaemonPortsOptions=Port=smtp,Addr=127.0.0.1, Name=MTA 更改为： DaemonPortsOptions=Port=smtp,Addr=yourip或者0.0.0.0, Name=MTA 然后m4 /etc/mail/sendmail.mc >/etc/mail/sendmail.cf 4.用户管理 认证的配置：修改/etc/mail/sendmail.mc中的字段，取消“TRUST_AUTH_MECH”一行和下一行“define”处的注释。（于sendmail.mc文件的第48www.03723.com、49）然后m4/etc/ mail/sendmail.mc>/etc/mail/sendmail.cf。 # chkconfig ——list saslauthd 开启认证 saslauthd 0:off 1:off 2:off 3:off 4:off 5:off 6:off # chkconfig ——level 35 saslauthd on # groupadd mailuser # adduser -g mailuser -s /sbin/nologin mike # adduser -g mailuser -s /sbin/nologin john # passwd mike # passwd john 密码都是123 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CVS 服务器配置高级议题。"3wanmei/" title="科颜氏"target="_blank ">科颜氏邮件发给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： # cat /etc/mail/access # Check the /usr/share/doc/sendmail/README.cf file for adescription # of the format of this file. (search for access_db in thatfile) # The /usr/share/doc/sendmail/README.cf is part of thesendmail-doc # package. # by default we allow relaying from localhost…… localhost.localdomain RELAY localhost RELAY 127.0.0.1 RELAY ltest RELAY 完成后makemap hash /etc/mail/access.db 6.#service sendmail restart # service sendmail restart 启动服务 Shutting down sendmail: Starting sendmail: [ OK ] Starting sm-client: [ OK ] # telnet localhost 25 Trying 127.0.0.1…… Connected to localhost.localdomain (127.0.0.1).
