Question

我有以下脚本处理电子邮件并将其保存到csv文件。我将使用mechanize lib来处理提取的电子邮件数据，以便在另一个Web界面上进一步处理。有时它可能会失败现在我可以捕获特定的电子邮件而不会有任何问题但是如何将被困电子邮件转发到我可以手动处理或查看它有什么问题的不同地址？

这是脚本

众所周知，POP3仅用于检索（知道或了解电子邮件如何工作的人），因此为了发送消息而使用POP3毫无意义，为什么我提到如何转发使用poplib到不同的电子邮件地址？作为一个问题。

完整的答案是 smtplib可以用于转发poplib捕获的电子邮件消息，您只需要捕获邮件正文并使用smtplib将其发送到所需的电子邮件地址。此外，正如Aleksandr Dezhin引用的那样，我会同意他的看法，因为有些SMTP服务器会对处理它们的邮件施加不同的限制。

除此之外，如果你在Unix机器上，你可以使用sendmail实现这一点。

如何将使用poplib捕获的电子邮件转发到其他电子邮件地址？
