Thanks for your message.  This question potentially has two factors. 

First, considering that your company has different domains (.com, ,net, .in), you will need to ensure that they are all aliased to the same tenant.  Your tenant admin can ensure that this is done correctly.

Second part is the distribution list - Microsoft Stream supports permissions based on Security Groups, so you can achieve what you are looking for using a SG created in your organization.  If you wish to see distribution lists supported, please add this to the ideas section.
