我怀疑电子邮件配置的电子邮件标题中的某些字段是空的。如果您粘贴邮件程序类和邮件程序配置，这将会很有帮助。 – Jesper 2014-09-23 14:05:52

我在发送附件时发生了类似的问题。

我需要改变attachments[:report]到attachments['report']

老：

def email_report(email, report) attachments[:report] = File.read(report) mail(to: email, subject: 'report') end

新：

def email_report(email, report) attachments['report'] = File.read(report) mail(to: email, subject: 'report') end

我怀疑类似的是发生在你的东西。

类似的问题在这里。请帮助 - http://stackoverflow.com/questions/29441305/cannot-create-firefox-browser-with-watir-webdriver – stack1 2015-04-04 00:44:31

我有同样的问题。我有以下几点：

include HTTParty

，并把它改成

require 'httparty'

，它为我工作。

希望这有助于。

我遇到了这个问题，因为我在'to'-field中设置了User-instance而不是user.email的值。

我有一个类似的问题，这是由于地址不是实际的电子邮件地址 – spartikus 2017-01-11 20:42:04
