Very nice and was looking for something local / sandbox to use with a CRM application to setup & learn its functionality but just local, no internet. I have a Proxmox server where I do things and now one can test / send emails from a specific application. How can one setup a local calendar that one can use for appointments / events / reminders etc. Is that also possible. That will enhance the functionallity testing / learning experience of this CRM system I try to understand.

Hello, the video was very helpful. Just a question, is possible to configure gmail or outlook instead of roundcude by just following the the similar steps? I am just a beginner with network configurations.

I'm experiencing troubles.
How do we create new mail accounts and users exactly?
I could create an account for my own Ubuntu. I'm the only one here. I can't create other users. Do i need to create users on the UbuntuOS for people who want to connect and send mails? Thanks

@ 17:40 you load the initial db setup. it defaulted to trying to use root and did not have access.
i needed to use the correct password.
in this case sudo mysql -u roundcubeuser -p roundcube <

This install is insecure plus you got postfix running without touching any config files for postfix or dovecot? huh.

Can connect these emails to use for outlook?
