[QUOTE="vvvvvvv, post: 2286156, member: 5151"] Not at the user level that I'm aware of. The email host can check if the server that it was sent from is in that domain's authorized list, but that's about it. You could try looking up who owns the C block of the IP it was sent from and notify the abuse contact there, but that doesn't always help, and it's also somewhat easy to spoof IP addresses. Email is very easy to spoof. You don't even need special tools. I'm surprised that businesses still use it for "secure" communication without any form of signing or encryption. Want passwords to a company's accounting database? Send an email to someone in the accounting office from an address like techsupport@ or [email]helpdesk@example.com[/email]. It works alarmingly often. I used to have a tshirt that said "There is no patch for human stupidity". Sent from my SCH-I535 using Tapatalk 2 [/QUOTE]
