The Multipurpose Internet Mail Extensions (MIME) type extends the email format to support text in character sets, non-text attachment, for example videos and message bodies with multiple parts. This guide will take you through the steps of adding MIME-Types to Website Panel (.Net).  

 

1. Log in to Website Panel (.Net). 

 

2. Click on “Web” and then “Websites”. 


 

 

3. Click on the domain you wish to add the MIME-type to. 


 

 

4. Click on the “MIME Types” tab. 


 

 

5. Click on “Add MIME”. 


 

 

6. Enter the extension and MIME-type you wish to enable in their respective fields. 


 

 

7. Click on “Update” once you’ve entered the required information. 


 

 

That’s it! You’ve successfully added a MIME-type. 

 

Here is a list of MIME-types if you are unsure what should be entered:
