| if sender is the same as the receiver then it's spam
I don't think I have ever seen spam with this characteristic.
I have, the header is something like this:
From: h0tsexxxxx(_at_)aol(_dot_)com
To: h0tsexxxxx(_at_)aol(_dot_)com
Maybe, and maybe not. Here is, in fact, a counterexample to both
assertions, from the depths of my mail archives:
Subject: Emacs 19.10 diffs
From: rms(_at_)gnu(_dot_)ai(_dot_)mit(_dot_)edu (Richard Stallman)
To: rms(_at_)gnu(_dot_)ai(_dot_)mit(_dot_)edu
Date: Sun, 30 May 93 03:20:53 -0400
Sent-Via-Bcc-To: Emacs pretesters
I sent a private email to someone recommending using grep to catch the
BCC's. Save the message and grep for valid destination addresses:
Am not sure about the example you provided. What was the recipient's
real email address ? Also, why would this guy send himself some mail
? Unless he's posting from the internet account of his mailing list.
You could also validate that both addresses aren't your own email
addresses.
For my own mailing list, the list member can see that
his post got through because he/she will receive a copy of it. If
not, he/she can contact me. So deleting an occasionnal valid message
isn't so bad for me as it is some other lists. (Just as long as I
keep my list spam-less).
