Having use this server for sometime. But since I had the problem in upgrading the 4.5.6. to 4.5.7 before. And I had Mike help out in the upgrading, therefore, I kept the server as it is for now. ( if not broken do not fix it)
However, since I have a new colleague and now need to add a user to the system and found the problem when the new user login the webmail:
Can anyone give hand?
