确定电子邮件地址的健康/有效性 [英] Determining the health/validity of an email address

问题描述

我知道如何通过脚本匹配电子邮件地址（特别是在他们将在 mailto：链接中的网页的上下文）。我的问题是如何在没有垃圾邮件地址的情况下验证它们是否正常？

剥离域名并验证其在端口25上的侦听是部分回答，但是

有没有办法将此添加到我管理的网站的维护脚本？

我不太在乎它写的是什么语言，只要它有效：）

解决方案

同意 Jay ：
全部完成这项工作的漂亮功能通常被关闭...

唯一的方法是发送电子邮件到该地址;即使如此，你也不是100％肯定的。

• 该地址可以是垃圾;没有人检查它。


• 邮箱已满（暂时？），您收到DSN


• SMTP服务器故障/停机

IMHO，不断检查域名（如果您不想获得黑名单，请轻松连接）以及反垃圾邮件工具（如akismet / spamhaus）以过滤用户注册。 / p>

Routine maintenance on a website often involves verifying that links are valid, flagging bad ones, etc.

I know how to match email addresses via a script (especially in the context of a web page where they'd be in mailto: links). My question is how would I verify they're OK without spamming the address?

Stripping-off the domain and verifying it's listening on port 25 is a partial answer, but doesn't handle verifying the username/alias.

Is there a way to add this to my maintenance scripts for websites I manage?

I don't really care what language it's written in, so long as it works :)

解决方案

Agree with Jay: All the nifty features built to do this particular job are generally turned off...

The only way is sending an email to that address; and even then, you're not 100% sure.

• That address can be garbage; nobody's checking it.
• Mailbox is full (temporarily?) and you get a DSN
• SMTP server glitches/outages

IMHO, keep checking the domain (go easy on connections if you don't want to get blacklisted) and antispam tools like akismet/spamhaus to filter user subsmissions.
