"Wrong Date" Emails == SPAM

On a regular basis, I get emails from vaguely reputable entities (airlines?!) sent with the wrong date. For example, on Wednesday I'll get a message "sent" on Monday. Because these messages show up out of order in a mail reader, and are marked "unread" among mostly "read" messages, they catch my attention. And sometimes I read them.

It's time to call this out for what it is: an annoying spamming technique designed to try and get my attention. And, like sending all your email flagged "High Importance," it gets old fast and makes you look bad.

There are plenty of time servers on the net. Plenty of bulk mailing mechanisms that don't get several days behind in getting the mail out. And plenty of docs on how to leverage UTC and offsets in your environment of choice.

So I don't believe anymore that a "misconfigured server" or "backed up bulk remailer" is to blame.

If I were an ISP, I'd think about creating spam filter rules that tweak an entity's rating every time bulk mail comes through with a date that's way off. Do this enough, and your messages go to my users' filtered spam folder.

sometimes you can go to earn the Pirates of the Burning Sea Gold for your own life and you can also get a lot of happiness in the game if you play the game well. you can brush the potbs gold to upgrade and then you are very strong. You think that you want to play the game well and then you can get the potbs Doubloon for your own. you can earn the potbs money alone and you can give some for your friends; it can make you very happy I think. As long as you play the game you can go to buy potbs Doubloon as the rewards in this game.

The game has a lot of LOTRO Gold, as long as you join to play this game you will get
them. you should try your best to earn as much Lord Of The Rings Gold as you can, so you are strong and no one can
fight you. you can go to buy LOTRO Gold in the game, so many other players want to play with you together. As long as you have the cheap Lord Of The Rings Gold you will be strong and you can go to kill the monsters to upgrade alone.

This is intentional. I just started receiving these backdated spam in my yahoo account. Some where dated from the 1930's. It's intentional, annoying, and if I ever could physically get my hands on someone responsible for generating that chit, they'd end up 6 feet under.
