I want to install in a Ubuntu Xenial Xerus Server under VMWare, all the packages that use a hosting web server or migth use (Apache+MySQL+phpmyadmin(protected by htaccess)+Webmin+ispConfig+Postfix+dovecot+Roundcube) and access to all of it trougth a noip ddns address So far I've manage to install the easy part, noip autostart, apache, mysql, phpmyadmin, webmin . ispConfig (in another instance of vmware), Postfix and dovecot are installed and aparently working but still don't know how to test them using my ddns address, and roundcube is installed too, aparently fine but I don't know how to log in, besides the configuration was a hard cause I had to manually set up the database connection in de conf files. I'm doing all this on my own just for learning purposes, to practice, to improve my knowledge, I love to learn and I'ld like to make this work properly. I have troubles understanding about virual server on apache, host and hostname and how to make them work with my noip, MX records to make noip works with mail. I've red a lot, believe me, a lot, but I feel that is about virtual server and hostname and mx records configuration... You can access to any of my 3 instances if you want to or guide me, please I beg you. Thank you very much in advance. Adrian Venezuela
