I have the following problem ...
I have configured two domains (domain1.com, domain2.com), two users with mail-adresses to their domains, e.g. firstname.lastname@example.org and email@example.com and two subdomains for login (mail.domain1.com and mail.domain2.com).
The problem now: I can login with both users using both subdomains.
It means I can use firstname.lastname@example.org and login at the loginscreen of mail.domain2.com - this I donīt want.
I want that the users can only login at their URL (email@example.com --> mail.domain1.com and firstname.lastname@example.org --> mail.domain2.com).
Whatīs wrong there?
