i have searched but can not find any answer.

my system is;

WHM 10.8.0 cPanel 10.8.2-R119
RedHat Enterprise 3 i686 - WHM X v3.1.0



i created an email account with only number password like 123456. then tried to login with outlook and domain.com/webmail, if i write 123456****** it logins. ****** may be what you want, 123456dfgdt for exp.

if password is not only number, its ok, it does not loging without exact password.

how can we solve this problem?
