MailShield

How to Spot a Phishing Email

• Suspicious sender address (e.g., random domain names)
• Urgent or threatening language (e.g., “Your account will be closed!”)
• Fake links (hover to preview before clicking)
• Unexpected attachments
• Spelling and grammar errors

Email Header Tips:

• Check if the From address matches the Return-Path or Reply-To address.
• Look for forged or suspicious Received fields that show unusual routing paths.
• Verify if SPF or DKIM signatures are present and valid.
• Watch out for missing or malformed Message-ID fields.
• Check if the email originates from unexpected countries or servers.
