Uninformatively, I am now away from the company and I can't check it now. I will send more information/attachment next Sunday (sorry about that). I have tried to reinstall 4 times. Now when I run "zmcontorl status" I find all services running fine. When I use FF on Windows, I can login, send email and check emails no problem. Also I can use Kmail to send and receive (SMTP, POP-ssl, IMAP-ssl). The problem is that our company wants employees to use the web-interface not POP, SMTP, and IMAP, and we have bunch of Linux/Mac users. I will try to use another Linux box and report back.
