If you’re running web host or email server using Exim or Sendmail as mail transfer agent (MTA), and found that emails or mail messages sent to you, your clients or users may occasionally lost or never arrived to the mailboxes, your mail server may fall victim to the mess of sender verification.如果您正在运行的网页主机或电子邮件服务器使用Sendmail的进出口或作为邮件传输代理（ MTA ） ，并发现，电子邮件或邮件发送给您，您的客户或用户可能偶尔会丢失或从未抵达的邮箱，您的邮件服务器可牺牲品混乱的发件人验证。 It’s the most likely cause of missing emails if you have verified that the email does not catch by spam filters or junk mail controls, and the mail server domain and IP address is not under any RBL (Real-Time Black Lists) block.这是最有可能的原因失踪的电子邮件如果您已确认的电子邮件不捕获的垃圾邮件过滤器或垃圾邮件的控制，以及邮件服务器的域名和IP地址是没有任何乡（实时黑名单）块。

The symptom of undelivered mail or bounced mail can also be checked and seen in Exim or Sendmail error log.症状交付邮寄或退回的邮件也可以进行检查，并从进出口或Sendmail的错误日志。 The mail usually get rejected by destination server (if destination server is your server, incoming email is lost, otherwise, outgoing mail is bounced) with the following messages:邮件通常会拒绝目的地伺服器（如果目标服务器是您的服务器，接收电子邮件的损失，否则，发送邮件是反弹）以下信息：

Sender verification is new measure to try to stop and block email spam infection.寄件人核查新措施，试图阻止和拦截垃圾邮件的感染。 Mail servers or more accurately the MTA such as Exim that comes with popular control panel such as cPanel and WHM uses a mechanism named sender callouts or callbacks to validate the complete incoming From: address of a remote sender as found in the email envelope is actually a real local account on the sending mail server.邮件服务器或更准确的MTA ，如进出口配备流行的控制面板等的WHM的cPanel和使用机制，命名为发件人标注或回调来验证完整的传入发件人：地址偏远发现发件人的电子邮件中信封实际上是一个真正的本地帐户的发送邮件服务器。 If the origin mail server returns the false value, the incoming mail will be reject and will not be accepted by the intended recipient’s MTA.如果原产地的邮件服务器返回错误值时，收到的邮件将反对和不能接受的收件人的三自爱国运动。

A bounced email will usually generate and indicate to the sender that the verification attempt fails.阿退回的电子邮件通常会产生并注明发件人，核查尝试失败。 However, as the sender doesn’t actually exist, so nobody will get the mail, and nobody knows what happen to the mail and why the email was never delivered.然而，由于发件人实际上并不存在，所以没有人会得到邮件，没人知道发生什么的电子邮件和电子邮件的原因是从未交付。 As not every mail host would bother you by making the mail server compliant with RFC standards, such as RFC 1123 which accept mails from the null sender, so you best bet to get mail safely and securely deliver is to make sure that your mail server able to properly handle the mails sent from those ignorant parties.由于并非每个邮件主机会打扰你，使邮件服务器兼容的RFC标准，如1123年的RFC接受电子邮件发送的无效，因此，您最好的选择收取邮件的安全和安全可靠地是要确保您的邮件服务器能要妥善处理好发送这些无知的当事方。

So if you’re the sender who found that your mail mysteriously disappear for unknown reason, make sure you send mail out with a real and actual mailbox user account name.所以，如果您发送谁发现，您的邮件神秘消失的原因不明，请务必发送邮件了一个真正的和实际的邮箱用户帐户的名称。 Using false or false mailbox name such as nobody@domain.com in hoping that nobody replies get back to you will likely to cause sender verification to fail, and no mail been routed and delivered.使用伪造或虚假的邮箱名称，如nobody@domain.com ，希望没有人答复回到您可能会导致发送失败的核查，没有电子邮件被发送和交付。

If you keep receiving mails especially from mailing lists or subscriptions that using invalid sender address, and you can’t help but need to receive the email, the only choice is to instruct your MTA to accept these emails.如果您不断收到电子邮件特别是从邮寄名单或订阅，使用无效的发件人地址，你不能不需要收到电子邮件后，唯一的选择就是您的MTA的指示接受这些电子邮件。 There are basically two choices on how to do it, firstly by creating a white lists which unblock those known email addresses, and secondly, disable sender verification altogether to avoid any future issues.基本上有两种选择就如何做到这一点，首先建立一个白名单而打破那些已知的电子邮件地址，其次，禁用发件人完全验证，以避免任何未来的问题。 Second option is much easy way, but you run the risk of receiving more spam.第二种选择是简单的方法很多，但你有可能得到更多的垃圾邮件。 Beside, the mail queue will also likely to grow larger or email will be rejected because the mail server will be accepting more faked spam messages.旁边，队列中的邮件也将可能增长较大或电子邮件将被拒绝，因为邮件服务器将接受更多的伪造的垃圾邮件。 However, you don’t have to worry about lost emails and undelivered emails anymore due to sender using non-existent email address.但是，您不必担心丢失电子邮件和未交付的电子邮件不再由于发件人使用不存在的电子邮件地址。 Here’sa few tutorials on how you can achieve these tasks in popular web hosting control panel - cPanel/WHM.下面几个教程你如何才能实现这些任务，流行的网页主机控制面板-的c Panel/的W HM。
