Feature Request: Allow sending from alias domains
Would there be a way to allow sending from alias domains? As in, when configuring an alias domain as a source to be directed to a different as the destination, could an option be added to allow sending from this alias (source) domain as well, so that all email accounts, aliases, and forwarders for the "destination" domain are duplicated for every domain alias as well?
An example would be I have a domain called firstdomain.tld but I want an alias domain of seconddomain.tld. When active, any email sent to secomddomain.tld will check if the address exists in firstdomain.tld and send to the recipient, i.e firstname.lastname@example.org. But what if I want to send an email from email@example.com. I can't currently because the address is not owned by firstname.lastname@example.org.
It would be great to have the option to enable this above the Active checkbox/option, similar to how alias and forwarder addresses have the Allow sending from this address option.
