在Linux上验证电子邮件地址 [英] verify email address on Linux

问题描述

我正在使用像 sendmail -bv [e-mail] 这样的命令来验证一些电子邮件地址，以确认地址是否有效，然后发送实际的电子邮件给人。
它适用于我测试的大多数网站。但是有时候，我正在使用一些网站的sendmail
，无论我在同一个网站上的地址名称为
，我都会通过。

I am using command like sendmail -bv [e-mail] to verify some email address to confirm the address is valid or not before sending actual email to people. it works for most sites I tested. But sometimes, I am using the sendmail for some website that will give me all pass no matter what the address name I put for the same site.

例如：

sendmail -bv [e-mail]

其中 yyyyyy 可以是任何传递命令的东西，并始终报告 [e-mail] 已验证。这似乎是正确的，但我认为这应该是错误的。为什么？

where yyyyyy can be anything that also passes the command and always reported out "[e-mail] verified". It seems correct but I think that should be something wrong behind. Why ?

其他命令检查linux上的邮件地址将是可靠和可用的，如何和什么命令这样做？

Other command checking mail address on linux will be reliable and available, how and what command does this?
