Monitoring and control of Cloudron mail server reputation.
-
This feature is essential in any professional mail server.
The reputation of a mail server is very important so that emails reach the recipient's inbox and not the spam box. It´s vital.
If you want to use the cloudron mail server in a professional way to send thousands and thousands of emails from different clients (emails that you cannot control), it is necessary to be able to monitor the percentage of bounces and percentage of complaints (spam) to take care of the server health .
If a client sends a lot of emails with our Cloudron mail server using bad practices (purchased databases, for example), by increasing complaints and bounces, it will considerably damage the reputation of our mail server. This can cause us to block the domain of the server for sending emails, with its corresponding consequences.
I propose to implement in the cloudron mail server the monitoring and control of those bounce and complaint rates associated with each sender email, that is, the email that caused those bounces and complaints. In such a way, that our cloudron mail server could automatically block the sending of emails with that sender if it exceeds certain limits / percentages that we must define.
For example, Amazon SES has a 5% bounce limit and a 0.1% complaint limit. Here you can see how Amazon has implemented this: https://prnt.sc/10apcxh
In addition, administrators should be notified by email when the mail server detects a rapid increase of these 2 percentages in a sender, and we can also block that sender manually.
Having a graph would help a lot to detect problemas before they happen: https://prnt.sc/10aq1l5
I am not an expert in mail servers, but an expert in this forum could confirm if what I say is that important or not.
In short: this would be to enable an effective control of the Mail Server Health. Something super important that would give Cloudron's mail server much more value over the rest of the competition. An important factor that would help more people to decide to use Cloudron.
Thank you.

https://lightmeter.io/ could at least serve as an inspiration. Later in they want to implement centralized insights.

@fbartels a very good contribution!!! maybe it would just be to add this application to cloudron (it is already packaged with docker) and join it with the mail server.

@mdreira Excellent suggestion.
We already have some of this information like bounce info, delivery info etc in the mail event log. I agree that it would be nice to have some graphs to digest that information better.

Great @girish !
Well, if graphical monitoring with the data we already have is relatively easy to implement, we can start with it and after that add control functionalities, so that Cloudron knows what to do with that data and we also have tools to block senders.
Because uncontrolled monitoring is of little use.

I've just added it to the App Wishlist for good measure:
