How to whitelist mail server

Whitelisting a mail server involves adding the server's IP address or domain name to a list of trusted senders, so that emails from that server are not flagged as spam or blocked by email providers. Here are the general steps to whitelist a mail server:

Step 1: Check the email provider's whitelist policy

Before whitelisting a mail server, check the email provider's whitelist policy to see if they have specific requirements or restrictions. Some providers may have a dedicated page for whitelisting or may require you to contact their support team.

Step 2: Gather the necessary information

To whitelist a mail server, you'll need to gather the following information:

• The mail server's IP address (e.g., 192.0.2.1)
• The mail server's domain name (e.g., mail.example.com)
• The mail server's reverse DNS (rDNS) record (e.g., reverse lookup of the IP address)

Step 3: Add the mail server to the whitelist

Once you have the necessary information, follow these steps to add the mail server to the whitelist:

a. Gmail (Google)

1. Sign in to your Gmail account.
2. Click on the gear icon and select "See all settings."
3. Go to the "Filters and Blocked Addresses" tab.
4. Click on "Create a new filter."
5. Enter the mail server's IP address or domain name in the "From" field.
6. Click "Create filter."
7. Select "Never send it to spam" and click "Create."

b. Microsoft Outlook/Office 365

1. Sign in to your Outlook or Office 365 account.
2. Go to the "Junk Email" settings.
3. Click on "Safe Senders" or "Safe Recipients."
4. Add the mail server's IP address or domain name to the list.
5. Click "OK."

c. Yahoo Mail

1. Sign in to your Yahoo Mail account.
2. Click on the gear icon and select "More settings."
3. Go to the "Filters" tab.
4. Click on "Add filter."
5. Enter the mail server's IP address or domain name in the "From" field.
6. Select "Never send it to spam" and click "Save."

d. Other email providers

For other email providers, such as AOL, Comcast, or Verizon, you may need to contact their support team or check their website for specific instructions on whitelisting a mail server.

Step 4: Verify the whitelisting

After adding the mail server to the whitelist, verify that emails from that server are no longer being flagged as spam or blocked. You can do this by sending a test email from the whitelisted server to your email account and checking if it arrives in your inbox.

Remember to regularly review and update your whitelist to ensure that only legitimate mail servers are allowed to send emails to your account.
