I finally received one of those spam e-mails that has the appearance of being sent from me to me. I have read here on the forums many times about this happening but can't seem to find the correct search terms to find the solution. It looks to this layman to have originated from Redmond, WA. I could be mistaken though. Here's the header if anyone can decipher any usable info.

Any ideas what steps I should take to prevent this in the future? I do have my default address set to fail.


Thanks, Mike

There is no real way to totally stop them. If I know or can guess your email address I can fake an email coming from you... it's very easy to do.


One thing you may do if it fits into your needs is to use a non-obvious name. "Mike" could be easily guessed - they may be sending it to mike, dave, bill, fred, susie, etc @ whatever domain they can find that exists.


In the mid-ish 1900's when Unix was starting to become popular in universities some guys tried to hack into several systems. They found that

The authors made a survey of several dozen local machines, using as trial passwords a collection of the 20 most common female first names, each followed by a single digit. The total number of passwords tried was, therefore, 200. At least one of these 200 passwords turned out to be a valid password on every machine surveyed.
By the way, one of the "authors" was the father of the punk-kid Robert T Morris that released the first publicized worm in 1988 that wrecked havoc.


In other words, don't be predictable in any way and you'll have a better chance of avoiding the jerks out there spamming.
