...done.Welcome to the OpenWebMail!This program is going to send a short message back to the developer,
so we could have the idea that who is installing and how many sites are
using this software, the content to be sent is:OS: Linux 4.18.0-80.11.2.el8_0.x86_64 x86_64
Perl: 5.026003
WebMail: OpenWebMail 2.54 20141206Send the site report?(Y/n) Y
sending report...# /usr/local/bin/openwebmail-tool --fixPermission and Ownership for openwebmail files have been fixed!5. Disable selinux and reboot# vi /etc/selinux/config
SELINUX=disabled6. Reload httpd# systemctl reload httpd7. Login to webmail URL with non-root user accounthttp://{hostname}/webmail2.配置
修改配置文件
vi /var/www/cgi-bin/openwebmail/etc/openwebmail.conf
- domainnames auto 改为 tsmt.com
- default_language en 改为 zh_CN.GB2312
- default_iconset Cool3D.English 改为支持中文 Cool3D.Chinese.Simplified
3.启动
service httpd restart
4.帐号
openwebmail是以系统用户和密码作为登录验证的
5.访问
以root用户名和密码登录，出现以下错误：
OpenWebMail ERROR:
无法写入 /var/log/openwebmail.log! (Permission denied)
查看该文件夹及文件权限，没有问题，甚至用CHMOD（chmod 777 /var/log/openwebmail.log)修改了一下,问题仍在。
通过编辑该文件：
vi /var/log/openwebmail.log
Sat Jan 23 22:22:51 2021 - [42810] (127.0.0.1) UNKNOWNUSER - send message - trying to connect to smtp server 127.0.0.1:25
Sat Jan 23 22:22:51 2021 - [42810] (127.0.0.1) UNKNOWNUSER - send message - connected to smtp server 127.0.0.1:25
得知，该错误是因为没有邮箱用户造成的。
列出用户列表：#cat /etc/passwd
找到邮箱用户：postfixuser:x:1006:1007::/home/postfixuser:/bin/bash
注册名：有密码：usrid:groopid::usrdir:命令解释程序
以该用户登录，问题依然如故。
命令执行chown postfixuser:postfixuser /var/log/openwebmail.log无效；
6.登录问题解决
#groupadd mymailuser //建立新组 mymailuser
#useradd tsmusr
#passwd tsmusr
#usermod -a -G mymailuser tsmusr (加入新建组）
#cd /home
#mkdir tsmusr
#cd tsmusr
#mkdir mymail
#chmod 777 mymail
#cd /
#chown -R tsmusr:mymailuser /home/tsmusr重新启动系统，以tsmusr用户登录，出现以下画面，成功。测试成功后，只要是centos下的帐户（不一定要加入特定组），均可登录成功。
7. 上述工作完成后，只能发送邮件，但不能接收邮件，我已经完成的工作如下：
postfix，dns,openwebmail有了上面这三个工作基础，我可以在自己的邮件服务器上创建邮箱帐号，如：tsmusr@tsmt.com,并可通过:http://mail.tsmt.com/webmail来发送邮件了。
下面我们继续安装一个工具Dovecot，就可以接收邮件了，至于邮件列表，需要安装mailman，我暂时不需要，就不介绍了，以后若需要，再来更新此篇文章。
Dovecot的安装没有新意，我的机器已安装好，这里就不介绍了。下面说说如何配置：
# vi /etc/dovecot/dovecot.conf
找到下面这行，去掉前面的注释和最后一个单词
protocols = imap pop3 lmtp
listen = *
login_trusted_networks = 192.168.1.0/24
# vi /etc/dovecot/conf.d/10-ssl.conf
将 ssl = required 改为 ssl = no
#vi /etc/dovecot/conf.d/10-auth.conf
把disable_plaintext_auth = yes改为disable_plaintext_auth = no
#vi /etc/dovecot/conf.d/10-master.conf
修改这一部分如下：
# Postfix smtp-auth
unix_listener /var/spool/postfix/private/auth {
mode = 0666
user = postfix
group = postfix
}
设定邮件存放位置
# vi /etc/dovecot/conf.d/10-mail.conf
mail_location = maildir:~/Maildir(与postfix相同）
重启系统
service dovecot reload或service dovecot start或service dovecot restart
上述工作完成后，postfix与dovecot是可以正常收发邮件了，但openwebmail仍然只能发邮件，不能收邮件。
8.问题解决
修改openwebmail 的一些配置文件[root@ser defaults]# vim /var/www/cgi-bin/openwebmail/etc/defaults/dbm.conf
dbm_ext .db
dbmopen_ext .db
dbmopen_haslock yes
smtpserver 192.168.1.202
[root@ser defaults]# vim openwebmail.conf
domainnames tsmt.com
smtpserver 192.168.1.202
authpop3_server 192.168.1.202
再次初始化openwebmail
[root@ser defaults]#/usr/local/bin/openwebmail-tool --init出现Y/N 时，按Y。把Postfix+Dovecot+Openwebmail 三者个格式统一下就行了
1.postfix 配置 main.cf
# vi /etc/postfix/main.cf
mail_spool_directory = /var/spool/mail
home_mailbox = /var/spool/mail/user
proxy_interfaces = 0.0.0.0
2.Dovecot 配置 10-mail.conf
vi /etc/dovecot/conf.d/10-mail.conf
mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u
3.Openwebmail.confvi /var/www/cgi-bin/openwebmail/etc/openwebmail.confmailspooldir /var/spool/mail注：main.cf的配置还是有问题，更新中
