I want to just ask and see if anyone has any interesting / unique thoughts on this "event" I am having.

In one of my yahoo webmail accounts I (fairly frequently) am receiving an email that has

[No Subject] in the subject line

and has "undisclosed-recipients" in the "to" address line

as well as " " ('nothing') in the "from" line.

Any thoughts? I figure it's from some kind of private emailing source,
except there is ALSO no message contained within. And I did even highlight the body of the msg IN CASE the font they used was white. But I was just wondering if anyone knew of another way a message like that might be used for hacking or ... what ever, just confirm or deny if you think it's some kind of "private" sender.

it's a new "spam" I seem to be getting,
I'm trying to think of ANYone I know who might be trying to send me a private message. Other than that, security issue... ?

Thanx
