I've got a question regarding to alias e-mail addresses. Here is what I do.
mydomain.com = Default Domain
The problem is that I want the user to login with "loginname", not "anothername". So basically I don't want to have aliases be able to login. Is there a way to achieve that somehow?
If you are wondering why I want to do that. The login mailaddresses (firstname.lastname@example.org) are not used for sending mails at all, just for the login. This is a restriction due to the security. I don't want to have public e-mail addresses which are used to login into any system.
