I have just setup my first ISP Confg server on Ubuntu 8.04 - kewl stuff. Version is 2.2.3 and I followed the Perfect Server for 8.04. I am having a problem however, I have followed the posts and scripts to change to a [Domain] style login . When I try to add a new email user, I fill the forms and when I click save I get the following error: Field: Username The user name has to contain a minimum of 4 and a maximum of 32 letters or figures and has to begin with a letter. I have not found any other posts that might relate to this error. EDIT: I found some posts - now digging deeper... sorry Any help is appreciated. Txs rolleye EDIT2: I used [Domain]_ and should have used [DOMAIN]_ - seems to be fixed now.
