Virtual Mailboxes with postfix

Problem Description
I want to use freedombox for hosting virtual mailboxes for email with different domains, but the same user for each of them.

I’ve managed to set up different domains, but they all point to the same mailbox, for a given user.

Can I setup postfix to do this? Or will Freedombox overwrite the configuration files if I do?

Welcome @stuartcnz !
FreedomBox mailserver follows a strict setup, which is necessary to manage this mailserver with installation, backups, certificates etc for people who do not have much knowledge. I guess for your usecase you have to install postfix, dovecot etc according to instructions (from their manuals) for virtual mailboxes. Since FreedomBox is Debian, you can do this in the terminal in addition to other FreedomBox apps. guess you have to uninstall postfix/dovecot as system app in FBX for this reason. But since I’m not an expert, there is maybe a way to adjust the config for virtual mailboxes in the FBX mailserver app.

Uninstalling the freedombox app and installing postfix/dovcot would defeat the purpose of using freedombox, which integrates an email setup very well. That is why I want to use it. It manages everything to keep it standards compliant and also handles account setup, configuration and passwords. If I can keep all of that and modify the config files for virtual mailboxes, I would be set. However, I will be migrating over existing email accounts from the same domain names, so must be sure that the configuration files modifications I make, won’t be rewritten by freedombox, as I can’t afford to lose the existing emails. If freedombox can’t be used in this manner, I will need to rebuild a new bare bones system to replace my out of date, current one. But would rather use freedombox, because it offers a whole lot more than just email and also takes so much of the work out of build an email server.

Exactly, this is the reason I like FreedomBox so much! I am running my email server and many other apps since two years now and really like it.
