3登录进主页面后，找到下方的“自主查询”选项，点击进入。
/iknow-pic.cdn.bcebos.com/54fbb2fb43166d22d4deb1174a2309f79152d28c"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/54fbb2fb43166d22d4deb1174a2309f79152d28c?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/54fbb2fb43166d22d4deb1174a2309f79152d28c"/>
4再进入“收信查询”里查看是否有记录，如果有记录，在操作栏中会显示对应的情况（可能会有被系统拦截、收信规则、黑名单等情况），如下图所示，这里有邮件被系统拦截了。
/iknow-pic.cdn.bcebos.com/2f738bd4b31c8701d71f16652b7f9e2f0608ff8c"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/2f738bd4b31c8701d71f16652b7f9e2f0608ff8c?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/2f738bd4b31c8701d71f16652b7f9e2f0608ff8c"/>
5点击右方的“添加到白名单”，邮件就能成功被找回。

可以使用其他QQ邮箱给没有接收到邮件的QQ邮箱发送邮件，如果有收到。可能是对方的邮件还没有成功发送，请联系对方发件人核实，例如对方已经退信。
