There´s nothing to do for that problem. There are lot´s of servers over the internet that allow any person to send emails with any domain name they desire. For example i can send emails from the presidente () presidencia gov ar. Try using certificated emails, that could help your customers/users to know if the mails they receive a really sent by you. ----- Original Message ----- From: "Tim Laureska" <hometeam () goeaston net> To: "security-basics" <security-basics () securityfocus com> Sent: Friday, March 05, 2004 3:59 AM Subject: email address "spoofed"
I'm not sure if "spoofing" is the correct term but here is what has happened: Someone is sending out email messages (with virus laden attachments) using our domain name ... they are addressed as coming from support () ourdomainname com (ourdomainame would be our actual domain name) which is an email address that we never set up. My question is how is this done and is there anything we can do to prevent this in the future?
