I have a server with Ubuntu Server 6.06 installed with ISPConfig and Uebimiau.
I had setup the mail server up and can accessing it with no problem, but my question is I can login to the mailbox with the same username with different domain.
For example, I setup a mailbox user email@example.com
. When I reach the webmail page, the login page requires me to login using email address, but I can login with firstname.lastname@example.org
or even user01@ with the default password for the user01... How can this be happened? Can anyone have any isea how to fix this?
Thanx a lot in advance!
