Centos
安装postfix默认centos 安装了postfix，使用默认的即可
yum -y install postfix1 配置postfix
实现使用postfix来发送邮件
配置如下：
grep -v '^#' /etc/postfix/main.cf | grep -v '^$' 输出结果：
queue_directory = /var/spool/postfix command_directory = /usr/sbin daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix mail_owner = postfix myhostname = mail.haitian.com mydomain = haitian.com myorigin = $mydomain inet_interfaces = all inet_protocols = all mydestination = haitian.com,$myhostname, localhost.$mydomain, localhost, $mydomain unknown_local_recipient_reject_code = 550 mynetworks = 172.16.0.0/16,172.16.0.0/8,172.16.89.0/24,127.0.0.0/8 relay_domains = $mydestination, $mynetworks alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases home_mailbox = Maildir/ debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5 sendmail_path = /usr/sbin/sendmail.postfix newaliases_path = /usr/bin/newaliases.postfix mailq_path = /usr/bin/mailq.postfix setgid_group = postdrop html_directory = no manpage_directory = /usr/share/man sample_directory = /usr/share/doc/postfix-2.6.6/samples readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES

10.0.3.3 mail.haitian.com1 测试邮件发送
简单测试
在Postfix服务器上执行命令：
echo "mail content" |mail -s test test@haitian.com1
测试结果：
test@haitian.com此邮件地址收到mail content内容的邮件
postfix日志：
postfix/pickup[15143]: 66D362604EA: uid=0 from=<root> postfix/cleanup[15483]: 66D362604EA: message-id=<20170608101648.66D362604EA@mail.haitian.com> postfix/qmgr[15144]: 66D362604EA: from=<root@haitian.com>, size=434, nrcpt=1 (queue active) postfix/smtp[15487]: 66D362604EA: to=<test@haitian.com>, relay=cdn11.intel-email.com[222.73.227.238]:25, delay=4.5, delays=0.11/0.03/3.4/0.97, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as 7CED62B991A04) postfix/qmgr[15144]: 66D362604EA: removed12345
表示已经正常发送
最后去test@haitian.com邮箱去查看是否已经接收到邮件，没有收到很可能被邮箱自己屏蔽了，将mail.haitian.com加入白名单。
