Final answer:
To globally permit a sender's email, you need to add it to a whitelist or safe sender list through your email service's settings or email security system. This process ensures that emails from the sender are not treated as spam and is crucial to manage carefully to prevent security risks.
Step-by-step explanation:
To globally permit a sender's email means to add the email address to a safe sender list or whitelist, ensuring that messages from this sender are not marked as spam or junk across all email accounts within an organization's email system. This process varies depending on the email service or email security system in place. However, most commonly, it involves accessing the email security settings or the email gateway system.
For example, in Microsoft Outlook, you would go to the Junk Email Options and add the desired email address to the Safe Senders tab. In a corporate environment, such as using Microsoft Exchange or Office 365, an administrator would use the Exchange Management Console or the Exchange Admin Center to configure organization-wide allow lists.
It's important that this action is taken with caution to avoid potential security risks associated with whitelisting email addresses, as this could open the door to phishing attacks if not managed properly.
