Zend Validate Email Address and Deep MX Checking

由 流过昼夜 提交于 2019-12-22 00:32:58
问题 I have started using Zend_Validate_EmailAddress with the mx and deep options set to true. I think I am getting some false negatives when it comes to MX records that have IP addresses in the reserved IP ranges. A good example is the MX records for harn.ufl.edu. It appear that it's failing because of IP addresses in the 128.0.0.0/16 range. It does however have one record that uses 8.6.245.30, which is not in the reserved range. Another example is the MX record for martinhealth.org. It's MX

Questions about implementing Domain class relationships & constraints in Grails

由 眉间皱痕 提交于 2019-12-22 00:18:51
问题 Using ArgoUML, I very quickly created this trivial representation of a few Domain classes (Person, Store, Product) and their relationships. I'm struggling with the implementation of the relationships. Below was my initial approach for the Person domain, but it seems that I am missing something important. class PersonToPerson { Person from Person to String relation static constraints = { relation(inList:["Friend to", "Enemy of", "Likes", "Hates"]) } static belongsTo = [ Person ] } class Person

Rails: Proper setup with DNS, Rack-rewrite etc for Heroku

由 折月煮酒 提交于 2019-12-22 00:11:05
问题 I have looked all over the internet but could not get one final solution to what I would expect to be the 100% proper setup of DNS etc to get the following result on Heroku.com: Using a mydomain.com to show the content at myapp.herokuapp.com Redirecting all traffic from http://mydomain.com to http://www.mydomain.com (including subfolders) I can get a bit of help from everywhere but nothing conclusive that will take care of the whole problem from DNS to rack-rewrite so that is why I am asking

面试题：从一个url地址到页面渲染完成 发生了什么 1.DNS解析 将域名地址解析为IP地址 浏览器的DNS缓存 系统DNS缓存 路由器DNS缓存 网络运营商DNS缓存 递归搜索 2.TCP链接 TCP三次握手 第一次握手，由浏览器发起，告诉服务器我要发请求了 第二次握手 由服务器发起 告诉浏览器我准备接受了 你赶紧发送吧 第三次握手 由浏览器发起 告诉服务器我马上就发了 准备接收吧 3.发送请求 请求报文 http协议的通信内容 4接受响应 响应报文 5渲染页面 遇见HTML标记 浏览器调用html解析器解析成Token并构建成dom树 遇见style/link标记 浏览器会调用css解析器处css标记并构建成cssom树 遇到script标记 调用js解析器 处理script代码（绑定事件 修改dom、cssom树） 将dom树和cssom树合并成一个渲染树 根据渲染树来计算布局 将各个节点颜色绘制到屏幕上（渲染） 注意： 这五个步骤不一定按顺序执行 如果dom树 或者cssom树被修改了可能会执行多次布局和渲染 往往实际页面中，这些步骤都会执行多次的 6.断开连接 TCP四次挥手 第一次挥手 由浏览器发起的 发送给服务器 我东西发送完了（请求报文），你准备关闭吧 第二次挥手 由服务器发起的 告诉浏览器我东西接受完了（请求报文） 我准备关闭了 你也准备吧 第三次挥手

　　我们在上一篇中完成了Exchange Server 2016 CU8的安装 《Exchange 2016部署实施案例篇-03.Exchange部署篇（下）》 ，接下来我们将进入配置相关内容，一开始的计划是将配置分为上、下2个盘符写配置，但在实际配置过程中发现截图是在有点多，所以只好将配置再次分为上、中、下3个篇幅写配置，还请谅解。 DNS配置（DNS轮询） 部署过Exchange Server的朋友可能知道，部署完成Exchange后，只能使用IP或者LocalHost方式访问，除非您在您的DNS里添加A记录，但看过活动目录部署篇《Exchange 2016部署实施案例篇-02.活动目录部署篇》的朋友可能知道，我们部署的域的域名是ITSoul.inter，那么我们如何使用Mail.Itsoul.cn访问那？ 那么我们首先就要在域的DNS里创建一个ITSoul.cn的DNS域，（如果您有业务系统也在使用ITSoul.cn域访问，并且走的都是公网的话，要把所有记录在内网DNS里创建一份）步骤如下 打开域的DNS，在正向查找区域右键选择"新建区域"如图所示： 点击完成后会弹出如下界面，并点击“下一步” 点击"下一步"后，会弹出如下界面，参照截图，选择"主要区域"并点击"下一步" 根据需求选择这个DNS作用域是同步到这个域还是林 输入您要创建的DNS作用域的名称，我们要使用Mail

Find original main domain name based on add-on domain name

由 馋奶兔 提交于 2019-12-21 23:11:03
问题 This may not even be possible but I'm trying to figure out the URL of the main domain for an add-on domain. Lets say for example the site is at mymaindomain.com. If I go to http://mymaindomain.com/cpanel (or :2082 or :2083) I get nothing. That is because mymaindomain.com is an add on domain for the hosting account. Lets say the primary domain on the account is myprimarydomain.com and this was the domain originally set up with the hosting account. However, this domain is no longer valid and

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 我们的设备在测试时发现有个别的主机，主程序DNS解释服务器域名失败。 最直接的表现就是 ping 126.com 显示： 对于这个问题，最直接的方式就是打开 /etc/resolv.conf 文件查看DNS服务器是否设置正确。结果该文件显示： search lan nameserver 127.0.0.1 博主用 strace ping 126.com 命令，分别比较了好的有问题的设备与没问题的设备。将输出信息用 meld 进行对比，结果看到在这里出现分歧： 可见， ping 命令在解释 "126.com" 域名时，是 connect 127.0.0.1:53 服务。而存在问题的一边，connect这个服务被拒绝了。 于是，博主可以分析得到，好的设备一定有一个服务进程bind了53端口，并提供了 DNS 服务。而有问题的设备一定是没有该进程。 博主在好的设备上运行 netstat -nap 找到了该服务： 同时我们又在问题的设备，执行 netstat -nap ，证实，有问题的设备上这个 dnsmasq 服务没有运行起来。 这里，博主查了些资料： Dnsmasq is a Domain Name System (DNS) forwarder and Dynamic Host Configuration

问题 I am sending a message via PHP's mail() with proper and complete headers. It has everything it is supposed to, and Hotmail likes the email itself. However, Hotmail is showing this in the source of the message: X-DKIM-Result: None X-Message-Status: n:0:n X-SID-Result: None X-AUTH-Result: NONE I tried to get them to Pass but only managed to turn the SID and AUTH to "Fail" causing SmartScreen to see the message as suspicious and delete it after ten days, whereas before it just seemed like spam
