Hi all, hope you can help me, i desisted to use CentOS because i couldn't get it to receive emails. So and as i new to this and most of examples are for Debian i change the OS to Debian 9. I used the "The Perfect Server - Debian 9 (Stretch) with Apache, BIND, Dovecot, PureFTPD and ISPConfig 3.1" to install everything in my server. ISPConfig Version: 3.1.14p1 now i have a different problem i can't send email, and when i try to load the "http://184.108.40.206/roundcubemail/installer" as i had it in CentOS it doent run, checking the instalation on Page3 , i can see that is a little bit more simple for debian but i doesn't include the web installer of the Roundcube. So i try to added following this example: https://www.rosehosting.com/blog/how-to-install-roundcube-webmail-on-debian-9/ but i still not opening could someone help me?.
