Email Spoofing

Email spoofing

Email spoofing refers to the process of sending an email message from one source ,but making it appear as though the email was sent from a different source .For example ,An email originates from user@domain.com but it appears to be from email@address.com .Another method of spoofing is to make the massage appear to come from an unknown user within your domain name .

This does not mean that yours email account was compromised .It means that the sender has fooled the mail client into believing  the email originated from a different address.

Email spoofing is the creation of email messages with a forged sender address - something which is simple to do because the core protocols do no authentication. Spam and phishing emails typically use such spoofing to mislead the recipient about the origin of the message.
