For more information, see Control automatic external email forwarding in Microsoft 365. Select one of the following actions from the Automatic forwarding rules dropdown list: • Automatic - System-controlled: This is the default value. This value is now the same as Off.

From <https://techcommunity.microsoft.com/t5/exchange-team-blog/all-you-need-to-know-about-automatic-email-forwarding-in/ba-p/2074888>

You can use outbound spam filter policies to control automatic forwarding to external recipients. Three settings are available:

• Automatic - System-controlled: This is the default setting. This setting is now the same as Off. When this setting was originally introduced, it was equivalent to On. Over time, thanks to the principles of secure by default, this setting was gradually changed to Off for all customers. For more information, see this blog post.
• On: Automatic external forwarding is allowed and not restricted.
• Off: Automatic external forwarding is disabled and will result in a non-delivery report (also known as an NDR or bounce message) to the sender.

you can change the default for your organization by adjusting the default message size restriction. 
Simply select recipients > mailboxes then click “. . .” and select Set default message size restrictions.

Outlook Web App (OWA) in Office 365 offers an easy way to “attach” a document as a link to where it’s saved on OneDrive for Business, a great option for sharing large files with your colleagues.

First and foremost, it there are two main categories of forwarding you'll need to pick from:

Option 1:  Forwarding an Office 365 mailbox - this scenario is typical when you want an Office 
365 login, whether it is because you need one for another Office 365 service (like Skype for Business 
(formerly known as Skype for Business (formerly known as Lync)) or SharePoint), or because you 
eventually will move all your email to Office 365. 
Option 2:  Forwarding for a simple email address (without a mailbox) - this is beneficial when 
there is no need to store any email on Office 365 for the address, and there is no reason to 
create an Office 365 account.

Before going further, I’d like to clarify your detailed requirement.

1.There is custom domain ‘mydomain.com’ in the Office 365 tenant.

2.You prefer to have an email address ‘username@mydomain.com’ and this email address don’t relative any mailboxes. So this email address don't need license.

3.The mail, which is delivered to the address ‘username@mydomain.com’, will be delivered to external mail box like ‘username@hotmail.com’.

You can create a Distribution Group (DG) with address ‘username@mydomain.com’ and add the ‘username@hotmail.com’ to this DG. You can follow the steps below.

1.Add the ‘username@hotmail.com’ to the external contacts. After logging into Microsoft Online Portal, click manages under Exchange. Select tab ‘Users and Groups’ and click External contacts. You can add the ‘username@hotmail.com’ to the contacts. For more information, please refer the following link.
