查看服务器状态：

mta   Stopped
postfix is not running

经查看mta服务是由postfix启动。

  • 查看系统是否已经对自带的sendmail和postfix进行关闭，端口25是否被占用，如果是请关闭并重启zimbra

  • 如果不是则执行/opt/zimbra/libexec/zmfixperms (run as root)

Refer：Zimbra 启动时mta无法启动 postsuper: fatal: scan_dir_push: open directory defer: Permission denied

错误：

opendkim: /opt/zimbra/conf/opendkim.conf: ldap://xxxx333.com:389/?DKIMSelector?sub?(DKIMIdentity=$d): dkimf_db_open(): Connect error
Failed to start opendkim: 0

原因：无法连接至ldap服务，检查ldap服务是否正常

Refer：ZCS 8.0 mta error with zmopendkimctl error

错误：Error: Queue report unavailable

We reviewed logs and services and we see that the MTA is down:

$ tail -f /var/log/mail.log

修改管理员账户密码

server.domain.com (https://server.domain.com:7071) 是当前运行的zimbra的域名或者IP地址，默认的http监听端口为7071 输入用户名： admin@domain.com 和密码，完成登录

在zimbra安装配置时创建了管理员账户，可以在web端的账户工具栏任何时候进行账户密码修改，选择administrator 用户并选择密码修改 也可以在命令行中运行zmprov进行管理员账户密码的修改：

zmprov sp admin@domain.com <password>
zmprov gaaa //列出所有管理员
zmprov sp admin q1w2e3r4 或 zmprov sp admin@wish.com q12e3r4  # 修改管理员账号密码

清除队列

查看发送队列数量:

/opt/zimbra/libexec/zmqstat

查看队列内容

mailq

删除队列

/opt/zimbra/postfix/sbin/postqueue -f

查看邮件队列

/opt/zimbra/postfix/sbin/postcat -qv EC753D0D00

解决：找其他服务器处理这个问题并修改配置

local_only = check_recipient_access lmdb:/opt/zimbra/conf/local_domains, reject

正常
