我有这样的代码:

for each in foo:
    if each not in foo2:
        msg = ("""
        Some message:
        %s
        """
        % (each))
        server.sendmail(from, to, msg)

它工作得很好而且花花公子。但是,当我尝试这样做时:

for each in foo:
    if each not in foo2:
        msg = "Some message:\n"+each
        server.sendmail(from, to, msg)

它发送空白电子邮件。可能还值得注意的是,each它始终是一个 URL。它与 SMTPlib 如何解析电子邮件有关吗?
