Error while Installing Webmail

While installing webmail, I get the following error:

"Warning: mkdir() [function.mkdir]: No such file or directory in /home/admispconfig/ispconfig/web/admin/update/install.php on line 40"

" The following error occurred: tmp_dir_error"

I thought it was a problem with the configuration of Fedora, but I made a new Install on another equipment and get the same message, can some one help me to correct this?

Thanks in advance

 

Which webmail are you using?

Uebimuiau, Squirrelmail, RoundCube, IlohaMail?
Did you use the pkg. file provided by ISPConfig or did you install it in a different way?

 

Sorry, we are using Fedora Core 6, with UebiMiau downloaded from the ISPConfig Downloads page, thanks for the help

 

Did you install it via the update manager within ISPConfig?
Is the error ocurring during this package installation?

 

Yeap, this work just fine, thanks a lot till
