RHEL4系統Sendmail郵件伺服器的架設

轉載:http://linux.chinaitlab.com/server/726302_2.html

  這次我們來學習Linux系統中的Sendmail伺服器的配置。(郵件伺服器的IP192.168.1.2 主機域名為mail.ltest.com)
  前提:首先我們 把DNS伺服器安裝OK 能夠解析,不明白的看http://linux.chinaitlab.com/server/725027.html
  1.首先安裝Sendmail所需軟體
  # rpm -q sendmail m4
  sendmail-8.13.1-2
  m4-1.4.1-16 已經默認安裝了,還需掛載第4張光碟,安裝與sendmail相關的軟體
  # 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。
  增加本地域和主機的FQDN,記住只是本地主機的FQDN和域名FQDN,不要添加其他域的,否則向外域發送郵件的時候會出現user unknown的錯誤:
  # cat /etc/mail/local-host-names
  # local-host-names - include all aliases for your machine here.
  ltest.com
  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 更改為:
  DaemonPortsOptions=Port=smtp,Addr=yourip或者0.0.0.0, Name=MTA
  然後m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
  4.用戶管理
  認證的配置:修改/etc/mail/sendmail.mc中的欄位,取消「TRUST_AUTH_MECH」一行和下一行「define」處的註釋。(於sendmail.mc文件的第48、49)然後m4 /etc/ mail/sendmail.mc>/etc/mail/sendmail.cf。
  # chkconfig ——list saslauthd 開啟認證
  saslauthd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
  # chkconfig ——level 35 saslauthd on
  建立用戶帳號
  # groupadd mailuser
  # adduser -g mailuser -s /sbin/nologin mike
  # adduser -g mailuser -s /sbin/nologin john
  # passwd mike
  # passwd john 密碼都是123
  設置郵件別名和郵件群發
  修改/etc/aliases文件實現郵件轉發和郵件列表:
  admin: mike 為郵件用戶mike設置別名admin
  testgroup: mike,john 實現群發 發給testgroup的郵件發給mike 和 john 以上2個可以分別測試
  #newaliases
  5.訪問控制設置
  更改/etc/mail/accesss文件,增加:
  # cat /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 RELAY
  localhost RELAY
  127.0.0.1 RELAY
  ltest.com RELAY
  完成後makemap hash /etc/mail/access.db < /etc/mail/access進行資料庫更新。
  6.#service sendmail restart
  # service sendmail restart 啟動服務
  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).
  Escape character is '^]'.
  220 localhost.localdomain ESMTP Sendmail 8.13.1/8.13.1; Sat, 17 Mar 2007 12:54:47 +0800
  ehlo localhost
  250-localhost.localdomain Hello localhost.localdomain , pleased to meet you
  250-ENHANCEDSTATUSCODES
  250-PIPELINING
  250-8BITMIME
  250-SIZE
  250-DSN
  250-ETRN
  250-AUTH DIGEST-MD5 CRAM-MD5 LOGIN PLAIN ——認證應該生效
  250-DELIVERBY
  250 HELP
  quit
  221 2.0.0 localhost.localdomain closing connection
  Connection closed by foreign host.
  7.安裝郵局服務
  # rpm -ivh dovecot-0.99.11-2.EL4.1.i386.rpm ——aid
  warning: dovecot-0.99.11-2.EL4.1.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e
  Preparing…… ###########################################
  1:perl-DBI ########################################### [ 20%]
  2:postgresql-libs ########################################### [ 40%]
  3:mysql ########################################### [ 60%]
  4:dovecot ########################################### [ 80%]
  5:perl-DBD-MySQL ###########################################
  把1-5這些軟體都安裝完畢才可以繼續下去呢,,,,
  # vi /etc/dovecot.conf在protocols = imap imaps 后添加pop3 pop3s
  啟動dovecot服務
  # service dovecot restart
  Stopping Dovecot Imap:
  Starting Dovecot Imap: [ OK ]
  # chkconfig ——level 35 dovecot on
  OK了 我們使用客戶機測試。
