Hi all,
we have many people that have registered to our newsletter and we are
getting every time more people who the email is unavailable. It''s there any
technique to detect such unavailable address ?
We tought about using a special email (like ne********@ourdomain.com) then
using a PHP script to catch the returning email and catch some text on them
and decide if we remove the address from our mailing list or not. It''s
possible with PHP ? It is the best solution ?
Thanks for answering.

当然，使用PHP是可行的，并且非常可行。无论是最好的
解决方案，您都可以自行决定。

Sure, it''s possible with PHP, and quite workable. Whether it''s the best
solution only you can decide.

你可以设置一个cron作业测试以下内容：
- 找到域名的MX记录
- 在套接字连接中尝试RCPT TO
- 标记emailaddres，因为错误时不可用
- 决定你的逻辑是什么删除电子邮件或重新检查它
（可能次数有限）以后
请参阅以下评论：
< ; HTTP：//nl2.php.net/manual/en/function.getmxrr.php>
You could set up a cron job testing for the following:
- find the MX record for the domain
- try a RCPT TO in a socket connection
- flag emailaddres as unavailable on error
- decide your logic wether to delete the emailaddres or recheck it
(perhaps a limited number of times) later
See the comments at:
<http://nl2.php.net/manual/en/function.getmxrr.php>
更加重要的是看注释：
注意：此功能不应用于地址
验证。只返回在DNS中找到的mailexchangers，
然而，根据> RFC 2821，当没有列出邮件交换器时，
hostname本身应该用作唯一的邮件交换器
优先级为0.
More improtantly see the Notes:
Note: This function should not be used for the purposes of address
verification. Only the mailexchangers found in DNS are returned,
however, according to >RFC 2821 when no mail exchangers are listed,
hostname itself should be used as the only mail exchanger with a
priority of 0.

...您可以将自己添加到代码中或作为返回的
MX记录，如果不存在/可以找到。如果你在
心中编写了这个后备代码，我认为你没有理由（/不应该从技术角度来看，b $ b b b），加载是别的东西）编写一个脚本，利用这个
函数来验证电子邮件地址。是的，这不是由这个
函数_alone_完成的，这就是恕我直言的这个说明。

... which you can add yourself in the code or as last item to the returned
MX records if none exist/can be found. If you code with that fallback in
mind, I see no reason why you couldn''t(/shouldn''t from a technical
standpoint, load is something else) write a script that makes use of this
function to validate an emailaddress. True, it cannot be done by this
function _alone_, that''s what IMHO this note is about.
