在chrome浏览器中输入https://mxtoolbox.com/打开其官网,或者直接点击此处,打开 MX tool box 官网 是的你没看错,MX tool box的官网就这么一点内容,干净的让人发指。为了凑字数,我只好把它的简介照抄了This test will list MX records for a domain in priority order. The MX lookup is done directly against the domain’s authoritative name server, so changes to MX Records should show up instantly. You can click Diagnostics , which will connect to the mail server, verify reverse DNS records, perform a simple Open Relay check and measure response time performance. You may also check each MX record (IP Address) against 105 DNS based blacklists. (Commonly called RBLs, DNSBLs)这段话什么意思呢?此测试将按优先级顺序列出域的MX记录。MX查找直接针对域的权威名称服务器完成,因此对MX记录的更改应立即显示。你可以单击Diagnostics功能按钮,它将连接到邮件服务器、验证反向DNS记录、执行简单的打开中继检查并测量响应时间性能。您还可以对照105个基于DNS的黑名单检查每个MX记录(IP地址)。(通常称为RBLs、DNSBLs)是不是看的有点稀里糊涂看不太明白?那就对了,要是MX tool box能将技术层面的东西讲的清新脱俗老少咸宜,还会被埋没吗?!对于我们新手小白来说,产品的技术含量怎么样不重要,重要的是简单好用就ok了。那我们话不多说直接来看它的功能吧。
