问题描述
我已经使用Tectite Formmail.PHP多年了。最后添加了Recaptcha ver 2（不可见模式）。它可以正常工作，除了它与 derive_fields 电子邮件字符串弄乱了。如果没有验证码，结果电子邮件的 发件人 字段正确包含填写我的表单的人的姓名和电子邮件地址，这是从中得出的值来自“实名”和“电子邮件”。
例如 Ralph Waldo
当我启用ReCaptcha时，结果电子邮件的 发件人 字段不希望地显示了我的托管帐户用户名和服务器地址：
例如*username@1a2b3c45.prod.phx1.example.net
如果我将表单恢复为标准标记并禁用Recaptcha（通过如下所示代码中使$ REQUIRE_CAPTCHA和$ RECAPTCHA_PRIVATE_KEY值无效），则会得到所需的 发件人 内容就像我以前一样。对于Formmail v 9.15和9.19，此行为是相同的。
如果这是Recaptcha的标准过程，则似乎没有记录。如果没有，解决办法是什么？
