Why You Need to Prevent Spam Emails

Spam emails not only clutter your inbox but can also be dangerous if they contain phishing links or malware. Learning how to stop spam emails ensures your email server remains secure and your communication stays reliable.

2. Open MailEnable Administration from the Start Menu or Desktop shortcut.
3. In the left panel, expand Messaging Manager, then click MailEnable, and select Post Offices.

Step 2: Restrict Relay to Prevent Sending Spam

Restricting relay ensures that only authorized users can send emails through your server. This is key to how do I stop spam emails from being sent from your domain.

1. In the left panel, navigate to:
   MailEnable > Servers > localhost > Connectors > SMTP.
2. Right-click SMTP and select Properties.
3. Under the Relay tab, you will see two options:
   • Allow relay for authenticated senders
   • Allow relay for local host only
4. Uncheck both options if you want to strictly control who can send emails through your server.

   This step helps prevent unauthorized users from sending spam emails from your server.

5. Click Apply, then OK to save changes.
   

Step 3: Restrict Sender Domain

Restricting sender domains can block emails from suspicious or spammy domains, a direct solution for how to stop receiving spam emails.

   MailEnable > Servers > localhost > Connectors > SMTP.
2. Right-click SMTP and select Properties.
3. Go to the Security tab. You will see several options to help prevent spam emails.

   • Sender email domain must be local or resolvable through DNS

     Ensures that only senders with valid, resolvable domains can send emails, reducing spam risks.

   • Authenticated senders must use address from their postoffice

     Prevents users from sending emails with fake addresses, directly answering how do I block spam emails.

   • Restrict the number of recipients per email

     Set a limit, e.g., 30, to prevent a single email from being sent to too many recipients, which is a common spam behavior.

   • Limit number of recipients per hour

     Set a limit, e.g., 500 per hour, to control mass emailing and reduce spam.

5. Click Apply, then OK to save the settings.
6. Test your settings by sending a test email from an unauthorized address or domain to ensure the restrictions work correctly.

By restricting sender domains, you can answer how do I block spam emails effectively.
