Need to prevent Email spoofing ?

"Email spoofing" is the email with a forged sender address - something which is simple to do because the email protocols have few parts of sender information, a sender name can be any kind of encoded text, design for display for human. Another type of sender info is design for email delivery over internet, which is being handled internally (inside email header, not design to display for human).  Since Email Address, Sender Name, Company Name do not need authentication.  Spoofing Email, Spam Mail or phishing emails typically use such spoofing to mislead the recipient !

Nowadays, a number of measures to address spoofing are available including: SPF, Sender ID, DKIM, S/MIME and Personal Authentication Certificates . Although their use is increasing, it is unlikely that most of the company still do not have such measures in place. Because their email system NOT well support those security, or may be the service providers' engineers are not yet have skill set to handle such security issues.
