Allow creating separate E-Mail Adresses for Domain Aliases
I would like to be able to create own e-mail addresses for Domain Aliases. Let's say i have example.com as domain and add example.net as alias, now i would like to create e-mail adresses for example.net (alias domain) only which are NOT available on example.com and vice versa.
Currently, when I am adding a new domain as alias, all e-mail accounts on the main domain automatically receive the emails through the alias domain, too. But it is not possible to write an e-mail from this address, the alias domain cannot be the sender atm.
I have to add the single domain to the subscription and create a htaccess or php redirect (because the Forwarding option does not allow a Let's Encrypt Certificate) just to be able to create an e-mail account.
