When the file size exceeds 15MB, I get the email with links instead of files.

Hi,

I'm sending all the uploaded documents I receive in a form to my email. However, when the total file size exceeds 15MB, I get the email with links instead of files. The email comes with this message:

Attachments: Because the total size is more than 15MB the uploads are not attached.

Is it possible to increase this file size limit? The problem doesn't seem to be with my email provider since I'm using MS Outlook and their file size limit is actually around 20MB.

Please be noted that we can only send up to 15MB of file attachments through the emails. This is due to most of the email service providers limit the attachments depending on their services and subscription plans.
