If someone sends you an email saying it's private & confidential...
 

...but you have had no prior communication or agreements with the individual or company -- does it have to remain private?

I would think no.

post the email here, i'll tell ya.

I agree, we need to see it to be sure

:1orglaugh

agreed.

That will be something!

It has nothing to do with GFY or Adult.

It would be pretty boring to most people here actually.

I'll have to call the attorney tomorrow morning and ask him I guess.

You can write and handle an email like you want. There are no official regulations regarding emails and even on curts emails do not have any authenticity.
So, it's up to you how to handle it, just post it and you will see what happen :)

It's up to you if you wanna keep it private or not.

Doesn't sound like it.

I'd call my lawyer and ask! :1orglaugh

it's hard to keep it private and confidential and the company that sent that to you knows it.

No, not unless they have put some clause in the subject line and even then it would be doubtful.
If the E-mail has been sent to you by mistake and you should realize that when opening the e-mail it might be a completely different matter.
