Hi Im still stuck with this error... For some reason I have checked all over google and cannot find a resolution to the problem.. It seems no matter what I do i cant get past this stage.. Can anyone help me with this matter Code: A problem was found with your Postfix virtual maps : No map sources were found in the Postfix configuration If I change the settings like it says in some google searches. Webmin > Servers > Postfix Mail Server > Virtual Domains > Domain mapping lookup tables = hash:/etc/postfix/virtual I then get this error. I tired to google this error but I don't get anything that comes close to a resolution. Code: The Read User Mail module is not setup to use the Postfix mail server. Either adjust its module configuration to match, or change the Virtualmin configuration. Can some one help me with this problem... Should I be using a different OS..
