电子邮件服务配置.doc

1 Linux版本：Ubuntu 10.042 实施思路、实施步骤、实施过程分析实施思路：在互联网上最觉的应用之一就是电子邮件，虽然套数数用户经常ISP或免费电子邮箱发信件，但 对于企业而言，为了能有效地对邮件进行管理，大多是自行架设邮件服务器。在Ubuntu Linux系统中，已内轩一套功能强大的邮件服务器Postfix。实施步骤：1. 安装Postfix命令：sudo apt-get install postfix安装Postfix服务器过程中系统会自行进行许多配置，首先首先会询问服务器安装的类型，我选择Internet Site,表示可以传送与接收Internet邮件。选择Postfix服务器类型后，接着要求配置“默认改善邮件来源的主机名称”，配置为。当用户通过系统发出邮件，但是其邮件地址中没注明网络域名名称，邮件地址中后面的文本将使用补全。2. Postfix的启动，停止，重新启动等命令启动服务：sudo /etc/init.d/postfix start停止服务：sudo /etc/init.d/postfix stop重新启动：sudo /etc/init.d/postfix restart3. Postfix基本配置(1)修改 main.cf 文件,先将其备份命令：sudo cp /etc/postfix/main.cf /etc/postfix/main.cf.bak命令:sudo gedit /etc/postfix/main.cfmyhostname = mail.goldenempire.asia#本机域名mydomain = goldenempire.asiamyorigin = $mydomainalias_maps = hash:/etc/aliasesalias_database = hash:/etc/aliases#收信域名，一定要有$mydomain不然不能使用收信mydestination =relayhost =#信任的，无须SMTP认证的地址范围mynetworks = /8mailbox_size_limit = 0recipient_delimiter = +inet_interfaces = all#邮件的存储方式，一定要有此设置home_mailbox = Maildirappend_dot_mydomain = noappend_at_myorigin = nosmtpd_helo_required = yesignore_mx_lookup_error = yesmessage_size_limit = 31457280#- virtual config -#本地邮件的投递方式，也可以使用maildroplocal_transport = maildrop#虚拟用户的投递方式，也可以使用maildropvirtual_transport = maildropmaildrop_destination_recipient_limit = 1virtual_alias_domains =virtual_alias_maps = proxy:mysql:/etc/postfix/mysql_virtual_sender_maps.cf, proxy:mysql:/etc/postfix/mysql_virtual_alias_maps.cfvirtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql_virtual_domains_maps.cfvirtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf#邮件存储的根目录virtual_mailbox_base = /home/domains#虚拟用户的ID，(数值参考实际系统的postfix用户的ID值)virtual_uid_maps = static:105virtual_gid_maps = static:114proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $smtpd_sender_login_maps $recipient_canonical_maps $relocated_maps transport_maps $mynetworks#- smtpd auth config -smtpd_sasl_security_options = noanonymoussmtpd_sasl_auth_enable = yes broken_sasl_auth_clients = yes#不投递本地系统帐号邮件local_recipient_maps = $alias_maps $virtual_mailbox_mapssmtpd_sender_login_maps = proxy:mysql:/etc/postfix/mysql_virtual_sender_maps.cf,proxy:mysql:/etc/postfix/mysql_virtual_alias_maps.cfsmtpd_reject_unlisted_sender = yessmtpd_recipient_restrictions = permit_mynetworks, reject_sender_login_mismatch, permit_sasl_authenticated, reject_unknown_sender_domain, reject_non_fqdn_hostname, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unauth_destination, reject_unauth_pipelining, reject_invalid_hostname, check_recipient_maps(2)修改master.cf 文件sudo gedit /etc/postfix/master.cfsmtp inet n - n - - smtpd flags=DRhu user=vuser argv=/usr/bin/maildrop -d $recipient配置couriersudo cp /etc/courier/authdaemonrc /etc/courier/authdaemonrc.baksudo vim /etc/courier/authdaemonrcauthmodulelist=authmysqlsudo cp /etc/courier/authmysqlrc /etc/courier/authmysqlrc.baksudo vim /etc/courier/authmysqlrcMYSQL_SERVER MYSQL_USERNAME extmailMYSQL_PASSWORD extmailMYSQL_PORT 3306MYSQL_OPT 0MYSQL_DATABASE extmailMYSQL_USER_TABLE mailboxMYSQL_CRYPT_PWFIELD passwordDEFAULT_DOMAIN domainMYSQL_UID_FIELD uidnumberMYSQL_GID_FIELD gidnumberMYSQL_LOGIN_FIELD usernameMYSQL_HOME_FIELD homedirMYSQL_NAME_FIELD nameMYSQL_MAILDIR_FIELD maildirMYSQL_QUOTA_FIELD quotaMYSQL_SELECT_CLAUSE SELECT username,password,domain, uidnumber,gidnumber, CONCAT(/home/domains/,homedir), CONCAT(/home/domains/,maildir), quota, name FROM mailbox WHERE username = $(local_part)$(domain) AND active = 1(3)创建/etc/postfix/sasl/smtpd.conf 加入下面的内容sudo gedit /etc/postfix/sasl/smtpd.confpwcheck_method:authdaemondlog_level:0mech_list:PLAIN LOGINallow_plaintext: trueauthdaemond_path:/var/run/courier/authdaemon/socket(4)图形日志配置sudo cp -R /var/www/extman/addon/mailgraph_ext /usr/local/mailgraph_ext修改mailgraph-initsudo gedit /usr/local/mailgraph_ext/mailgraph-initMAIL_LOG=/var/log/mail.log(5)添加开机自启动项
