If a website is secure, this doesn't happen.
If a person has a secure setup, this doesn't happen.
This has probably been asked a thousand times but here goes, how do people send you SPAM and make the "From" address show the recipients of such. I have seen this happen with several of me email accounts and it is usually for some cheap Internet pharmaceuticals or something like that. I have always done my best to examine the headers to find some domain or something I can block but more recently, they have been getting trickier about it. It's really weird seeing junk mail with your own address as the from and return address as well as the receiver.
If this is a common practice of today's spammers, is there a convinient way to use whitelist/blacklist type filters to block them? I can't imagine blocking my own email address although I don't know that I need to be able to email myself.
It just seems the spammers keep getting better and we need to be able to head them off at the pass.
