linux下sendmail的安装与配置

1.要求利用Linux系统下的Mail服务，能够收发邮件；2.突出邮件服务器的特点，能够用OutLook收发邮件；一．配置DNS1. 使用vi /etc/named.conf打开DNS主配文件，然后找到最后一行，并在最后一行上面添加下列内容：zone "" IN {type master;file ".zheng";allow-update { none; };};zone "1.254.10.in-addr.arpa" IN {type master;file "10.254.1.fan";allow-update { none; };};2. 迚入/var/named目录，将该目录下的localhost.zone和named.local 分别拷贝为.zheng和10.254.1.fan，如下:[root@localhost root]# cd /var/named/[root@localhost named]# lslocalhost.zone named.ca named.local[root@localhost named]# cp localhost.zone .zheng[root@localhost named]# cp named.local 10.254.1.fan[root@localhost named]# ls10.254.1.fan localhost.zone named.ca named.local .zheng然后编辑.zheng和10.254.1.fan两个文件，将这两个文件分别改为如下内容：两文件中后面的点（.）不可少[root@localhost named]# vi .zheng$TTL 86400@ 1D IN SOA . . (42 ; serial (d. adams)3H ; refresh15M ; retry1W ; expiry1D ) ; minimum1D IN NS .1D IN MX 5 .ns 1D IN A 10.254.1.253mail 1D IN A 10.254.1.253[root@localhost named]# vi 10.254.1.fan$TTL 86400@ IN SOA . . (1997022700 ; Serial28800 ; Refresh14400 ; Retry3600000 ; Expire86400 ) ; MinimumIN NS .253 IN PTR .253 IN PTR .3. 将/etc/resolv.conf文件中DNS设为本机IP [root@localhost named]# vi /etc/resolv.conf nameserver 10.254.1.253search localhost4. 测试DNS，如下图，说明成功。

二．配置sendmail1.配置主配文件[root@localhost named]# vi /etc/mail/sendmail.cf将# SMTP daemon optionsO DaemonPortOptions=Port=smtp,Addr=127.0.0.1, Name=MTA改为：# SMTP daemon optionsO DaemonPortOptions=Port=smtp,Addr=10.254.1.253, Name=MTA[root@soft8 named]# vi /etc/xinetd.d/ipop3service pop3{socket_type = streamwait = nouser = rootserver = /usr/sbin/ipop3dlog_on_success += HOST DURATIONlog_on_failure += HOSTdisable = no 将这里的yes改为no }[root@soft8 named]# vi /etc/xinetd.d/imapservice imap{socket_type = streamwait = nouser = rootserver = /usr/sbin/imapdlog_on_success += HOST DURATIONlog_on_failure += HOSTdisable = no 将这里的yes改为no }[root@soft8 named]# service xinetd restart[root@localhost mail]# sendmail -btADDRESS TEST MODE (ruleset 3 NOT automatically invoked) Enter <ruleset> <address>> $=wlocalhost.localdomainlocalhost[127.0.0.1]>[root@soft8 named]# vi /etc/mail/local-host-names# local-host-names - include all aliases for your machine here. [root@localhost mail]# sendmail -btADDRESS TEST MODE (ruleset 3 NOT automatically invoked) Enter <ruleset> <address>> $=wlocalhost.localdomainlocalhost[127.0.0.1]>[root@soft8 named]# vi /etc/mail/access# Check the /usr/share/doc/sendmail/README.cf file for a description # of the format of this file. (search for access_db in that file)# The /usr/share/doc/sendmail/README.cf is part of the sendmail-doc # package.## by default we allow relaying from localhost...localhost.localdomain RELAYlocalhost RELAY127.0.0.1 RELAY RELAY10.254.1.253 RELAY[root@soft8 named]# cd /etc/mail[root@soft8 mail]# makemap hash access.db < access 添加用户yzl，kk, 在这里设的用户密码与用户名相同[root@localhost mail]# useradd yzl[root@localhost mail]# passwd yzlChanging password for user yzl.New password:BAD PASSWORD: it's WAY too shortRetype new password:passwd: all authentication tokens updated successfully. [root@localhost mail]# useradd kk[root@localhost mail]# passwd kkChanging password for user kk.New password:BAD PASSWORD: it's WAY too shortRetype new password:passwd: all authentication tokens updated successfully.[root@localhost mail]#2.重启sendmail发送邮件测试[root@localhost mail]# service sendmail restart关闭sendmail：[ 确定]关闭sm-client：[ 确定]启动sendmail：make: *** Warning: File `virtusertable.db' has modification time in the future (2008-12-31 00:56:51 > 2008-12-30 20:48:43.607615)make: warning: Clock skew detected. Your build may be incomplete.[ 确定]启动sm-client：[ 确定][root@localhost mail]# 如下图设置outlookLinux邮件服务器安装与配置本人最新升级公司的linux邮件服务器，觉得最新的spamassassin功能非常好，所以整理一下安装步骤供网友参考。
