If you encounter an issue where a personal email address (such as Hotmail, Gmail, etc.) is not accepted as a referee email, it is likely due to the requesting company's policy. Some companies have restrictions that prevent the use of personal email addresses for references.
To resolve this, you should contact the company directly that requested your references.
They may provide guidance or have the ability to override the setting to allow the use of a personal email address.
