[vqadmin] my vqadmin doesnt work

[bahareh]

Hi every body I installed vqmail for the first time on linux7.X�� I did every thing that was in the “install instruction” But when I connect to it this error appears:   �   �Authentication Failed Username unknown   vQadmin was unable to determine your username, which means your webserver is improperly configured to run with this CGI.� For security reasons, this script will not run without Apache htaccess lists.   Pleas could you tell me what should I do   Regards Bahare Abedin
