Is this an exploit of the email system of some sort? I receive a great deal of spam every day, and my accounts in Yahoo and Gmail sometimes show me spam emails from the future. Yes, the future.
Sometimes it will give me a day ahead when they send it, which could mean they are a day ahead via time zones, but sometimes I have also seen a week ahead, but rarely I find emails sent a month in the future.
Are these spammers exploiting a part of email that allows them to spoof the timestamp of the email? I have always been curious how they are managing to send me mail from the future.
