Forward user mail to "Default mail forwarding address" don't work on postfix

When I creating a new Virtual Server, there's a section called IP address and forwarding. Within there, I set Default mail forwarding address to my email, but after that I didn't receive mail from the created user.

How to reproduce:

We have email admin@myserver.com and want to receive on it all cron mail from user of new virtualserver.

We press Create Virtual Server, set name to example1.com, set Default mail forwarding address = admin@myserver.com

Virtualmin creates new server with user example1.com, and adds those aliases to /etc/postfix/virtual

example1.com@example1.com example1.com
example1.com example1.com
@example1.com admin-myserver.com

So, after that all mail to anything@example1.com redirects correctly to user admin-myserver.com, but cron mail sends to example1.com, not to example1.com@example1.com, and it isn't redirects to admin-myserver.com.

For solve this we must create aliases like this:
example1.com@example1.com example1.com
example1.com admin-myserver.com
@example1.com admin-myserver.com

or maybe like those variants:
example1.com@example1.com admin-myserver.com
example1.com admin-myserver.com
@example1.com admin-myserver.com

example1.com example1.com@example1.com
@example1.com admin-myserver.com

Maybe this is only postfix-specific, because postfix don't associate example1.com address with @example1.com wildcard, but postfix goes by default and, I think, this issue must be fixed.

Or maybe I do something wrong with configuring, but I can't see how to fix my problem.

I will fix this in the next Virtualmin release (3.86) by having the domain owner's email forwarded to the same address. You can make an equivalent change now by going to Edit Mail and FTP Users -> example1 -> Mail forwarding settings , and entering the address in the "Forward to other addresses" box.
