生产环境记得放开80端口


vim /var/www/html/postfixadmin/setup.php

#修改
if ( $f_imap_open == 0)



#创建管理员账户
http://mail.abc.com/postfixadmin/setup.php


#登陆管理用户账户
http://mail.abc.com/postfixadmin/login.php



总结启动的服务：

systemctl start dovecot  
systemctl start postfix
systemctl start mysqld 
systemctl start httpd
systemctl start saslauthd

如果在创建邮箱时，vmail目录没有生成，需要自己创建

mkdir /home/vmail

chown -R vmail:vmail /home/vmail
chmod 755 /home/vmail

-------------------环境准备三--------------------

启用ssl加密

cd /etc/pki/tls/certs
make server.key  #输入个密码
openssl rsa -in server.key -out server.key
make server.csr
openssl x509 -in server.csr -out server.crt -req -signkey server.key -days 3650
chmod 400 server.*

vim /etc/postfix/main.cf
#添加到最后
smtpd_use_tls= yes
smtpd_tls_cert_file = /etc/pki/tls/certs/server.crt
smtpd_tls_key_file = /etc/pki/tls/certs/server.key
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtpd_tls_loglevel = 0
smtpd_tls_auth_only = yes

vim /etc/postfix/master.cf
#去掉注释
smtps       inet   n       -       n       -       -       smtpd
  -o smtpd_tls_wrappermode=yes

vim /etc/dovecot/conf.d/10-ssl.conf
ssl = yes
# 第12,13行:
ssl_cert = </etc/pki/tls/certs/server.crt
ssl_key = </etc/pki/tls/certs/server.key

vim /etc/postfix/master.cf
#取消注释
submission inet n       -       n       -       -       smtpd

#重启服务
systemctl restart dovecot
systemctl restart postfix
