推荐答案

检查是否完全没有意义你不知道邮箱，尽管它可能存在，甚至是由人类照顾。

It's also utterly pointless to check as you have no idea if the mailbox, though it may exist, is even attended to by a human being.

你不能，除非发送电子邮件给它并要求跟随此链接点击返回您的网站，通常使用查询字符串来标识它是哪个电子邮件。即便如此，您也无法保证电子邮件地址在十分钟后仍然有效 - 有些服务可以为您提供十分钟的有效电子邮件，以应对需要注册的网站，但您不希望被垃圾炸毁。



有些机制 看起来 就像它们应该工作一样，例如要求读取响应等等第四，但它们完全由用户正在阅读电子邮件的软件自行决定，并且大多数在发送之前要求用户进行确认。



悲伤，但是真的：这取决于垃圾邮件发送者，他们迄今为止滥用了所有机制来识别实时电子邮件帐户并将其作为目标......所以合法需求也不再有效。

You can't, except by sending an email to it and requiring a "follow this link" click back to your website, usually with a query string to identify which email it was. And even then, you have no guarantee that the email address is still valid ten minutes later - there are services which give you a valid email for ten minutes to cope with sites that require registration but you don't want to be bombarded with rubbish.

There are mechanisms which look like they should work, such as requiring a "read response" so so forth, but they are entirely at the discretion of the software the user is reading emails with, and most ask the user for confirmation before sending it.

Sad, but true: this is down to spammers, who have abused every mechanism so far in order to identify "live" email accounts and target them...so legitimate needs no longer work either.

取决于电子邮件服务提供商。
