一、安装部署Postfix
1.Postfix简介
Postfix是Wietse Venema在IBM的GPL协议之下开发的MTA（邮件传输代理）软件
Postfix是Wietse Venema想要为使用最广泛的sendmail提供替代品的一个尝试
Postfix试图更快、更容易管理、更安全，同时还与sendmail保持足够的兼容性
2.设置计算机名称、关闭防火墙、关闭selinux、语言设置为中文、卸载系统sendmail、添加hosts域名映射
hostnamectl set-hostname localhost.localdomainvi /etc/selinux/config
SELINUX=disabledlocalectl set-locale LANG='zh_CN.UTF-8'systemctl disable firewalldyum remove -y sendmail*vim /etc/hosts
127.0.0.1 mail.swireb.cn swireb.cn
3.安装Postfix
yum install -y postfix*
4.Postfix默认安装路径
rpm -ql postfix|more
/etc/pam.d/smtp
/etc/pam.d/smtp.postfix
/etc/postfix
/etc/postfix/access
/etc/postfix/canonical
/etc/postfix/generic
/etc/postfix/header_checks
/etc/postfix/main.cf
/etc/postfix/master.cf
5.Postfix服务配置
#备份文件
cp /etc/postfix/main.cf /etc/postfix/main.cf.back#修改配置文件
vim /etc/postfix/main.cf#myhostname参数设置主机名称
# The myhostname parameter specifies the internet hostname of this
# mail system. The default is to use the fully-qualified domain name
# from gethostname(). $myhostname is used as a default value for many
# other configuration parameters.
#
#myhostname = host.domain.tld
myhostname = mail.swireb.cn #mydomain参数设置域名
# The mydomain parameter specifies the local internet domain name.
# The default is to use $myhostname minus the first component.
# $mydomain is used as a default value for many other configuration
# parameters.
#
mydomain = swireb.cn #myorigin参数设置邮箱后缀
# The myorigin parameter specifies the domain that locally-posted
# mail appears to come from. The default is to append $myhostname,
# which is fine for small sites. If you run a domain with multiple
# machines, you should (1) change this to $mydomain and (2) set up
# a domain-wide alias database that aliases each user to
# user@that.users.mailhost.
#
# For the sake of consistency between sender and recipient addresses,
# myorigin also specifies the default domain name that is appended
# to recipient addresses that have no @domain part.
#
#myorigin = $myhostname
myorigin = $mydomain#inet_interfaces参数设置监听地址
# The inet_interfaces parameter specifies the network interface
# addresses that this mail system receives mail on. By default,
# the software claims all active interfaces on the machine. The
# parameter also controls delivery of mail to user@[ip.address].
#
# See also the proxy_interfaces parameter, for network addresses that
# are forwarded to us via a proxy or network address translator.
#
# Note: you need to stop/start Postfix when this parameter changes.
#
inet_interfaces = all #监听所有网卡
#inet_interfaces = $myhostname
#inet_interfaces = $myhostname, localhost
#inet_interfaces = localhost#inet_protocols参数设置打开IPV4或者IPV6
# Enable IPv4, and IPv6 if supported
inet_protocols = ipv4#mydestination参数设置能够接收信件的主机名称
# The mydestination parameter specifies the list of domains that this
# machine considers itself the final destination for.
#
# These domains are routed to the delivery agent specified with the
# local_transport parameter setting. By default, that is the UNIX
# compatible delivery agent that lookups all recipients in /etc/passwd
# and /etc/aliases or their equivalent.
#
# The default is $myhostname + localhost.$mydomain. On a mail domain
# gateway, you should also include $mydomain.
#
# Do not specify the names of virtual domains - those domains are
# specified elsewhere (see VIRTUAL_README).
#
# Do not specify the names of domains that this machine is backup MX
# host for. Specify those names via the relay_domains settings for
# the SMTP server, or use permit_mx_backup if you are lazy (see
# STANDARD_CONFIGURATION_README).
#
# The local machine is always the final destination for mail addressed
# to user@[the.net.work.address] of an interface that the mail system
# receives mail on (see the inet_interfaces parameter).
#
# Specify a list of host or domain names, /file/name or type:table
# patterns, separated by commas and/or whitespace. A /file/name
# pattern is replaced by its contents; a type:table is matched when
# a name matches a lookup key (the right-hand side is ignored).
# Continue long lines by starting the next line with whitespace.
#
# See also below, section "REJECTING MAIL FOR UNKNOWN LOCAL USERS".
#
#mydestination = $myhostname, localhost.$mydomain, localhost
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
#mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain,
# mail.$mydomain, www.$mydomain, ftp.$mydomain#mynetworks参数设置指定受信任SMTP的列表（受信任的SMTP客户端允许通过Postfix传递邮件）
# Alternatively, you can specify the mynetworks list by hand, in
# which case Postfix ignores the mynetworks_style setting.
#
# Specify an explicit list of network/netmask patterns, where the
# mask specifies the number of bits in the network part of a host
# address.
#
# You can also specify the absolute pathname of a pattern file instead
# of listing the patterns here. Specify type:table for table-based lookups
# (the value on the table right-hand side is not used).
#
mynetworks = 0.0.0.0/0
#mynetworks = $config_directory/mynetworks
#mynetworks = hash:/etc/postfix/network_table#relay_domains参数设置转发邮件域名
# The relay_domains parameter restricts what destinations this system will
# relay mail to. See the smtpd_recipient_restrictions description in
# postconf(5) for detailed information.
#
# By default, Postfix relays mail
# - from "trusted" clients (IP address matches $mynetworks) to any destination,
# - from "untrusted" clients to destinations that match $relay_domains or
# subdomains thereof, except addresses with sender-specified routing.
# The default relay_domains value is $mydestination.
#
# In addition to the above, the Postfix SMTP server by default accepts mail
# that Postfix is final destination for:
# - destinations that match $inet_interfaces or $proxy_interfaces,
# - destinations that match $mydestination
# - destinations that match $virtual_alias_domains,
# - destinations that match $virtual_mailbox_domains.
# These destinations do not need to be listed in $relay_domains.
#
# Specify a list of hosts or domains, /file/name patterns or type:name
# lookup tables, separated by commas and/or whitespace. Continue
# long lines by starting the next line with whitespace. A file name
# is replaced by its contents; a type:name table is matched when a
# (parent) domain appears as lookup key.
#
# NOTE: Postfix will not automatically forward mail for domains that
# list this system as their primary or backup MX host. See the
# permit_mx_backup restriction description in postconf(5).
#
relay_domains = $mydestination#alias_maps参数设置邮件别名路径
# The alias_maps parameter specifies the list of alias databases used
# by the local delivery agent. The default list is system dependent.
#
# On systems with NIS, the default is to search the local alias
# database, then the NIS alias database. See aliases(5) for syntax
# details.
#
# If you change the alias database, run "postalias /etc/aliases" (or
# wherever your system stores the mail alias file), or simply run
# "newaliases" to build the necessary DBM or DB file.
#
# It will take a minute or so before changes become visible. Use
# "postfix reload" to eliminate the delay.
#
#alias_maps = dbm:/etc/aliases
alias_maps = hash:/etc/aliases
#alias_maps = hash:/etc/aliases, nis:mail.aliases
#alias_maps = netinfo:/aliases#alias_database参数设置邮件别名数据库路径
# The alias_database parameter specifies the alias database(s) that
# are built with "newaliases" or "sendmail -bi". This is a separate
# configuration parameter, because alias_maps (see above) may specify
# tables that are not necessarily all under control by Postfix.
#
#alias_database = dbm:/etc/aliases
#alias_database = dbm:/etc/mail/aliases
alias_database = hash:/etc/aliases
#alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases
6.开启Postfix服务（服务统一在后面开启）
二、安装部署cyrus-sasl
1.cyrus-sasl简介
#Saslauthd服务作用：提供SMTP用户验证，检查用户名和密码是否正确，基于系统shadow文件实现验证配置
2.安装cyrus-sasl
#默认安装的有这个认证软件cyrus-sasl
rpm -qa|grep cyrus
cyrus-sasl-lib-2.1.26-23.el7.x86_64
cyrus-sasl-2.1.26-23.el7.x86_64#没有软件的话yum安装一下
yum install -y cyrus-sasl*
3.开启Saslauthd服务，提供SMTP用户验证（服务统一在后面开启）
三、安装部署Dovecot
1.Dovecot简介
#Dovecot是一个开源的IMAP和POP3邮件服务器，支持Linux/Unix系统，作为IMAP/POP3服务器，Dovecot为邮件用户代理（MUA）提供了一种访问服务器上存储的邮件方法#PS:Dovecot并不负责从其他邮件服务器接受邮件，Dovecot只是将已存储在邮件服务器上的邮件通过MUA显示出来
2.安装Dovecot
yum install -y dovecot*
3.Dovecot服务配置
#开启POP3协议，默认只开启了IMAP的认证
vim /etc/dovecot/dovecot.conf
# Protocols we want to be serving.
protocols = imap pop3 lmtp #开启POP3# A comma separated list of IPs or hosts where to listen in for connections.
# "*" listens in all IPv4 interfaces, "::" listens in all IPv6 interfaces.
# If you want to specify non-default ports or anything more complex,
# edit conf.d/master.conf.
listen = * #监听全部
4.Dovecot服务配置禁止SSL登录，同时设置邮箱路径
vim /etc/dovecot/conf.d/10-ssl.conf
# SSL/TLS support: yes, no, required. <doc/wiki/SSL.txt>
# disable plain pop3 and imap, allowed are only pop3+TLS, pop3s, imap+TLS and imaps
# plain imap and pop3 are still allowed for local connections
ssl = no vim /etc/dovecot/conf.d/10-auth.conf
# Disable LOGIN command and all other plaintext authentications unless
# SSL/TLS is used (LOGINDISABLED capability). Note that if the remote IP
# matches the local IP (ie. you're connecting from the same computer), the
# connection is considered secure and plaintext authentication is allowed.
# See also ssl=required setting.
disable_plaintext_auth = novim /etc/dovecot/conf.d/10-mail.conf
# See doc/wiki/Variables.txt for full list. Some examples:
#
# mail_location = maildir:~/Maildir
mail_location = mbox:~/mail:INBOX=/var/mail/%u
# mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n
5.开启Dovecot服务（服务统一在后面开启）
四、创建用户、邮箱、开启服务
1.创建用户
useradd -s /sbin/nologin test
echo 123456|passwd --stdin test
2.创建邮箱并设置权限
mkdir -p /home/test/mail/.imap/INBOX
chown -R test.test /home/test
3.开启服务
systemctl enable postfix
systemctl enable dovecot
systemctl enable saslauthdsystemctl restart postfix
systemctl restart dovecot
systemctl restart saslauthd
4.检查端口是否以及在启用（此时监听25、110、143端口）
yum install -y net-tools #安装TCP/IP工具箱netstat -tnl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:110 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN
五、删除用户和邮箱
1.删除普通用户
userdel -r yangwn
#直接删除家目录、邮件目录
2.删除虚拟用户
vi /etc/passwd /etc/shadow /etc/group /etc/gshadow #虚拟用户在这里删除（有虚拟用户的信息行直接删除）rm -rf /home/test #删除家目录rm -rf /var/spool/mail/test #删除邮件目录
六、配置域名映射
1.域名解析设置
主机记录 记录类型 线路类型 记录值 优先级 TTL 最后操作时间 操作@ A 默认 95.214.177.67 - 600 2020-08-05 01:44:37 修改暂停删除mail A 默认 95.214.177.67 - 600 2020-08-05 01:44:56 修改暂停删除mail MX 默认 swireb.cn. 5 600 2020-08-05 17:05:49 修改暂停删除
2.本地hosts文件解析设置
C:\WINDOWS\system32\drivers\etc
172.1.1.15 mail.swireb.cn swireb.cn
七、Postfix别名设置
1.Postfix别名简介
#Postfix服务器中可以使用aliases机制属性邮件别名和邮件群发功能，也可以创建用户组，将用户加入某个组中，实现邮件群发
在/etc目录下存在aliases和aliases.db两个文件
aliases是文本文件可以编辑修改
aliases.db是数据库文件，是由aliases文本文件通过命令newaliases生成
2.Postfix别名设置
#设置admin别名组
vim /etc/aliases
admin: yangwn,test#生成数据库文件
newaliases#修改Postfix配置文件确保邮件别名路径和邮件别名数据库路径已经设置
vim /etc/postfix/main.cf
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases#让别名文件生效
postmap hash:/etc/postfix/access
postalias hash:/etc/aliases#重启sendmail服务
systemctl restart postfix
3.测试发送邮件给别名组
#此时root用户给admin@swireb.cn发送邮件，则会群发到yangwn@swireb.cn和test@swireb.cn邮箱中
echo "This is test Mail"|mail -s "Test Mail Sendmail" admin@swireb.cn#切换用户接受邮件
su - yangwnmail
Heirloom Mail version 12.5 7/5/10. Type ? for help.
"/var/spool/mail/yangwn": 1 message 1 new
>N 1 root Fri Aug 7 14:53 18/565 "Test Mail Sendmail"
八、使用Foxmail客户端进行邮件测试
1.使用Foxmail客户端进行配置
2.外网发送邮件失败，报RCPT错误（客户端的IP地址不被服务端信任）
3.查看邮件日志
tail -f /var/log/maillog
Aug 7 13:36:24 mail postfix/smtpd[7910]: connect from unknown[14.205.134.67]
Aug 7 13:36:25 mail postfix/smtpd[7910]: NOQUEUE: reject: RCPT from unknown[14.205.134.67]: 454 4.7.1 <1014575812@qq.com>: Relay access denied; from=<test@swireb.cn> to=<1014575812@qq.com> proto=ESMTP helo=<PC>
Aug 7 13:36:25 mail postfix/smtpd[7910]: disconnect from unknown[14.205.134.67]
4.解决报错问题
#mynetworks参数设置指定受信任SMTP的列表（受信任的SMTP客户端允许通过Postfix传递邮件）
vim /etc/postfix/main.cf
# Alternatively, you can specify the mynetworks list by hand, in
# which case Postfix ignores the mynetworks_style setting.
#
# Specify an explicit list of network/netmask patterns, where the
# mask specifies the number of bits in the network part of a host
# address.
#
# You can also specify the absolute pathname of a pattern file instead
# of listing the patterns here. Specify type:table for table-based lookups
# (the value on the table right-hand side is not used).
#
mynetworks = 0.0.0.0/0
#mynetworks = $config_directory/mynetworks
#mynetworks = hash:/etc/postfix/network_table#重启sendmail服务
systemctl restart sendmail
九、使用mail命令进行邮件测试
1.安装mail命令软件（默认自带）
yum install -y mailx
2.使用mail命令进行邮件发送测试
#发送一份邮件给外网邮箱
echo "This is test Mail"|mail -s "Test Mail Sendmail" 1014575812@qq.com
3.使用mail命令查看邮件
#邮件的保存路径：/var/spool/mail#mail命令默认查看当前用户的邮件（查看其他用户su命令切换后再进行查看）
mail
Heirloom Mail version 12.5 7/5/10. Type ? for help.
