Firstly thank you so much for taking the time to explain all that. I REALLY appreciate it.
So lets see if I understand what you have said.
I got all that until the "@hisbusiness.com" example. I’m not sure if you’re saying that it can be done or cant be done. I think you’re saying it can be done as long as I own the domain (hisbusiness.com) however I don’t see how my ownership of could be checked as part of the authentication process.
So to make it easier for you to reply this is what I would want to do.
- use lyb@mybox.com as the authnticated email to access my box.
- I connect to miab that is installed on mybox.com from mydomain.com with the box email - lyb@mybox.com.
- I have an alias that is lyb@mydomain.com and is an authenticated user on lyb@mybox.com
- I then connect to miab on mybox.com with lyb@mydomain.com
- The from address in the recipient email account then shows lyb@mydomain.com even though it was sent via miab lyb@mybox.com.
What I am a bit lost on is these different references in your example -
Allowed sender
Authenticated user
Alias
And it seems that some of these are setup in miab admin? yes?
And some of these are setup in Roundcube etc, where as Interspire Email Marketer (that I’m using) doesn’t have that feature that I know of to add an “identity”, or perhaps they just call it something else.
