How to block spoofing in mail enable plesk windos

Spoofing is a common threat in email systems, where an attacker sends an email with a fake sender's address (spoofed email) to trick the recipient into believing it's coming from a legitimate source. To block spoofing in MailEnable on Plesk Windows, you can follow these steps:

Method 1: Using MailEnable's built-in SPF (Sender Policy Framework) feature

1. Log in to your Plesk control panel and go to MailEnable > Settings > SPF.
2. Enable SPF by checking the box next to Enable SPF.
3. In the SPF Record field, enter the following text: v=spf1 a mx include:_spf.google.com ~all
4. Click Apply to save the changes.

Method 2: Using MailEnable's built-in DKIM (DomainKeys Identified Mail) feature

1. Log in to your Plesk control panel and go to MailEnable > Settings > DKIM.
2. Enable DKIM by checking the box next to Enable DKIM.
3. In the DKIM Key field, enter the public key provided by your email service provider (e.g., Google).
4. Click Apply to save the changes.

Method 3: Using Plesk's built-in SpamAssassin feature

1. Log in to your Plesk control panel and go to Mail > SpamAssassin.
2. Enable SpamAssassin by checking the box next to Enable SpamAssassin.
3. Configure the SpamAssassin settings to your liking (e.g., adjust the spam score threshold).
4. Click Apply to save the changes.

Additional tips

• Make sure your domain's DNS records are properly configured to include the SPF and DKIM records.
• Consider implementing additional security measures, such as greylisting, to further reduce the risk of spoofing attacks.
• Regularly monitor your email logs to detect and respond to potential spoofing attempts.

By following these steps, you can help protect your email system from spoofing attacks and ensure the integrity of your email communications.
