Since 9/19/2006 when I last emptied my Junk folder, my personal email address has 1.65GB (yes, gigabytes) of Spam/Viruses in it. That is in my opinion a sign of a serious problem.
Oh yea, a few weeks ago, we began auto-rejecting email from certain blacklisted servers, which drastically cut down on spam. And still it almost hit the 2GB mark.
Imagine how much wasted electricity spam filtering costs due to consuming CPU cycles and hard drive I/O. Not to mention the financial cost.
On a side note, for Thunderbird users:
I like to keep a mail archive, I do so using the trash. I just don’t empty. But I don’t want my “Junk” in there. So what I do is periodically delete it.
Edit: See comment #1 for a better way, or for my way, read on.
First close Thunderbird. In your profile, find your
Junk. Delete it and create a blank. Or in any Unix OS:
rm -r Junk touch Junk
Then open up Thunderbird, right click on the Junk folder (will still show # of items, though none exist), select “Compact”. It will soon reset to 0. Done. Nothing mixed in your trash. Perhaps a nice extension would be a hard delete, one that didn’t go to the trash, but just wiped the contents away.
