如何在ActionMailer中捕获错误异常 [英] How to catch error exception in ActionMailer

问题描述

问题是如何在ActionMailer发送邮件时捕获异常。对我来说听起来是不可能的，因为在这种情况下，ActionMailer应该发送邮件到mailserver，如果mailserver返回错误，ActionMailer应该显示这个错误。我只想计算未送达的邮件。

The problem is how can I catch exception in delivering mail by ActionMailer. For me it sounds impossible, because in this case ActionMailer should sent mail to mailserver, and if mailserver returns error, ActionMailer should show me this error. I am interested only in counting undelivered mails.

您有什么想法可以实现吗？
谢谢！

Do you have any ideas how to implement this? Thanks!

推荐答案

我在控制器中使用这样的东西：

I'm using something like this in the controller:

 if @user.save
      begin
      UserMailer.welcome_email(@user).deliver
      flash[:success] = "#{@user.name} created"
      rescue Net::SMTPAuthenticationError, Net::SMTPServerBusy, Net::SMTPSyntaxError, Net::SMTPFatalError, Net::SMTPUnknownError => e
        flash[:success] = "Utente #{@user.name} creato. Problems sending mail"
      end
      redirect_to "/"
