Ruby on rails Rails 3:无法使用自定义：发件人=>地址发送电子邮件

我正在尝试发送电子邮件，但电子邮件永远不会使用my:from=>代码，而是使用gmail smtp设置中的“from”来发送电子邮件。例如，电子邮件到达时说：email@gmail.com而不是来自：support@mydomain.com，并在日志中显示使用发件人发送的电子邮件：contact@mydomain.com这是我发明的初始化器

我怎样才能解决这个问题？现在真让人心烦：谢谢你的帮助

我正在使用Gmail并按如下方式设置smtp设置：

Gmail正在改变你的身份。如果您不想修改，请使用自己的邮件服务器

在使用邮件界面和/或谷歌服务器时，有一个关于如何设置不同发件人的问题

IMAP/POP用户注意：如果您通过POP或IMAP电子邮件客户端（如Outlook）访问Gmail，并希望发送带有自定义发件人地址的邮件，则您有两种选择。我们建议您将电子邮件客户端配置为两个传出SMTP服务器，一个用于Gmail，另一个用于其他地址。或者，您也可以使用Gmail的出站服务器，使用不同的发件人地址。如果您已经配置了备用地址，您的邮件将从以下地址发送：otheraddress@domain.com，发件人：username@gmail.com，而不管您选择了哪个自定义配置

你必须先为gmail启用你的第三方地址。检查上面链接的导轨。

IIRC-gmail将设置不同的地址，但是用户仍然会看到它来自gmail。

它真的只是gmail吗？在线上有很多教程，包括railscasts，其中显示了如何使用gmail smtp进行配置，但也在mailer方法中使用自定义：from=>进行配置？

ActionMailer::Base.smtp_settings = {
     :address              => "smtp.gmail.com",
     :port                 => 587,
     :domain               => "mydomain.com",
     :user_name            => "email@gmail.com",
     :password             => "mypassword",
     :authentication       => "plain",
     :enable_starttls_auto => true
     }

   def reset_password_instructions(user)
     @user = user
     @url  = "http://localhost:3000"
     mail(:to => user.email,
          :from => "support@mydomain.com",
          :subject => "recover your password"
          )
   end
end
