我有一个Plone 3.2.1网站，上面安装了Products.PloneFormGen，它有一个表单，配置了一个发送到谷歌应用程序分发组的邮件程序。然而，一旦提交该表格，就意味着向通讯组发送一封电子邮件；此时它正在发送4。
为了调试并确保不是通讯组在做一些奇怪的事情，我在网站上安装了Products.PrintingMailHost，每次提交表单时都可以在控制台中看到打印了4次的电子邮件。有人建议我，这个问题可能与Zope数据库冲突错误有关，但当我在前台模式下加载任何客户端时，我没有看到任何与此相关的内容，这让我相信这可能不是问题所在，或者我找错了地方。
如果我从表单中删除mailer apater，它将阻止它发送任何电子邮件。
如果有帮助的话，我已经在前台模式下加载一个客户端时包含了输出：

尝试编辑并保存表单。这可能会消除有关缺少操作适配器的警告。
在该编辑表单中，查看所选的操作适配器，并查看是否有您不期望的额外适配器。但听起来你可能已经这么做了。
如果它是一个简短的形式：只需重新创建它并删除旧的。：-）
我想知道表单是否记住了一些动作适配器，这些适配器已不可用，但无论如何都是通过获取找到的。这是一个很长的机会
检查邮件适配器。也许你有一些覆盖添加了太多的电子邮件地址？可能收件人在"收件人"、"抄送"one_answers"密件抄送"字段中？
