Limit email for Cloudron domain only

[serverpost]

My initial email setup experience:

I run Cloudron on digitalocean. After installing RoundCube I was not able to log in. So I proceeded to create mailboxes by importing manually created CSV file with users / emails copying existing users in Cloudron.

Not sure if this is the way to do it, but I wanted to try a phased approach. Finally after turning the incoming mail on, I was able to log in.

In either way I have fully functioning webmail without much hassle which is very impressive!

Now to my question:

Is there a meaningful way to limit the incoming and outgoing email for just for cloudron domain?

It is all cloudron users have cloudron emails on their accounts and can use them only for internal communication?

(The initial account setup and reset email can be done in alternative ways)

Thoughts?

If I understand the question correctly, you want a setup where emails are to be limited only within the domain. External mails should not be received or sent.

We don't have a way to do this, no. Quite interesting feature request, I have to say

@girish if it’s about completely blocking any outside email communication then blocking outbound communication on port 25 is a way the achieve this. This way every mail directed to an outside server would eventually result in a non delivery as the destination cannot be connected.
