I have a general question covering few aspects. On my dedicated server I have 1 IP. I installed Virtualmin on Ubuntu Hardy, and also Postfix email. I keep on getting the message of Certificate being invalid. I also want to install webmail en some outlook emails are not delevered. The one user using vista and Outlook 2007 keep on getting a problem that when trying to sent email, she need to supply username and password.
I am lost now - any one available to help??
