Hello to all.. i just finished installing ispconfig to centos 4.4, and setup my 3 different domains there, create account/email each. What ive noticed is.. the user that i created from the other domain, can actually login to the other. Like for example.. i have a domain, domain.com, other.com. i created a user from domain.com which is, user1, and has an email of firstname.lastname@example.org, then i create another user2 for other.com and has the email of email@example.com when i finished installing squirrelmail as my front end, and go to mail.domain.com to try to login user1 for an email of firstname.lastname@example.org, yes.. it successfully logged in. but.. when i try to login user2 on that particular squirrelmail front end, and yes.. it does, and automatically got a email@example.com which i did not in the first place created. im just confused about this, supposedly user2 can just have firstname.lastname@example.org and can login to mail.other.com, and cannot logged as email@example.com in domain.com please.. help..
