资源摘要信息:"Object.identical.js是一个JavaScript工具,用于比较两个对象或数组的相等性。这个方法检查两个给定的参数是否满足以下条件: 1. 如果比较的是两个对象,则这两个对象必须具有完全相同的属性,并且对应的属性值也必须完全相等。 2. 如果比较的是两个数组,则这两个数组的元素顺序和内容都必须完全相同。 3. 对于原始数据类型,比如数字、字符串、布尔值等,使用严格的等于操作符(===)进行比较。 需要注意的是,Object.identical方法对于对象的比较是基于深度相等性的,即使两个对象的属性顺序不同,只要它们的值相同,也会被认为是相等的。例如,对象{ x: 19, y: 83 }和对象{ y: 83, x: 19 }会被认为是相同的。 此外,该方法的实现需要依赖于JSON.stringify()函数,因为Object.identical()在比较对象或数组时,会将它们转换成JSON字符串,再进行比较。这意味着如果对象或数组中包含不能被JSON.stringify()有效转换的值,比如函数或循环引用等,那么Object.identical()将不能正确地比较它们。 在使用Object.identical()方法时,还应注意不要对原始数据类型(number、string、boolean、null、undefined)使用扩展运算符(Object扩展),因为这会导致不必要的复杂性和潜在的错误。扩展原始类型并不是一个好主意,它可能会导致代码难以维护和理解。 在某些情况下,直接使用===操作符可能更合适,尤其是在比较简单类型的值时,这样做可以避免JSON.stringify()带来的额外开销。 最后,Object.identical()方法是在MIT许可下发布的,这意味着该方法可以被采取、改进、重新分配和重复使用。这为开发者提供了在遵守MIT许可协议的前提下自由使用和修改代码的可能性。"

请翻译:202.192.1.5 is making SMTP connections which indicate that it is misconfigured. Some elements of your existing configuration create message characteristics identical to previously identified spam messages. Please align the mail erver's HELO/EHLO 'icoremail.net' with proper DNS (forward and reverse) values for a mail server. Here is an example: Correct HELO/DNS/rDNS alignment for domain example.com: - Mail server HELO: mail.example.com - Mail server IP: 192.0.2.12 - Forward DNS: mail.example.com -> 192.0.2.12 - Reverse DNS: 192.0.2.12 -> mail.example.com Correcting an invalid HELO or a HELO/forward DNS lookup mismatch will stop the IP from being listed again. Points to consider: * Alignment: it is strongly recommended that the forward DNS lookup (domain name to IP address) and rDNS (IP to domain) of your IP should match the HELO value set in your server, if possible * The IP and the HELO value should both have forward and rDNS, and should resolve in public DNS * Ensure that the domain used in HELO actually exists! Additional points: * According to RFC, the HELO must be a fully qualified domain name (FQDN): "hostname.example.com" is an FQDN and "example.com" is not an FQDN. * The domain used should belong to your organisation. * HELO is commonly a server setting, not DNS. Contact your hosting provider for assistance if needed. You can test a server's HELO configuration by sending an email from it to helocheck@abuseat.org. A bounce that contains the required information will be returned immediately. It will look like an error, it is not. Please examine the contents of this email. If all settings are correct, you have a different problem, probably malware/spambot. Again, the HELO we are seeing is 'icoremail.net'. The last detection was at 2023-05-27 13:35:00 (UTC). For information on misconfigured or hacked SMTP servers and networks, please see this FAQ: https://www.spamhaus.org/faq/section/Hacked...%20Here's%20help#539 CSS listings expire a few days after last detection. You can always open a ticket (or update an existing one) to inform us when and how the situation was been secured.
