One reason phishing e-mails are so convincing is that more than 95 percent of them forge the "from" line so that the message looks like it's from the spoofed company. If e-mail gateways could verify that messages purporting to be from, say, Citibank did in fact originate from a legitimate Citibank server, messages from spoofed addresses could be automatically tagged as fraudulent and thus weeded out.
第二句试译：
如果电子邮件网关能够证实声称来自花旗银行的邮件的的确确由花旗银行的合法服务器发来，来自被欺骗地址的邮件就有可能自动被标为欺诈邮件，因而被剔除。
抛开原文不说，这样合乎逻辑吗？还是译文本身有问题？
