Ram storage resuirment

Hello can i install mailcow on server with 4gb ram storage?

As per docs a minimum of 6 GB is recommended. If you disable solr, and probably clamav as an antivirus scanner too, it should work with 4 GB RAM too. Disabling SoGo would even get more free memory, but you’ll lose any webmail at this point.

There are config options to disable each individual service:

SKIP_CLAMD=y
SKIP_SOLR=y
SKIP_SOGO=y

I installed one at 4GB server once, at idle its using about 80%. But it spike to 90% once in a while. It is doable. But I would go with the minimum requirement which is better for daily usage.

Right now using on 8GB - idling at 55-60%

Hello @Sifo123 Yes you can install Mailcow on a server with 4GB of RAM but it is the minimum required. For better performance, 6GB+ is recommended with more users or heavy traffic; Monitor performance & consider upgrading if needed.

No, it is actually 6 GB:

If you disable things like Solr and ClamAV and SOGo you can run it on 4 GB, but at your own risk.
But what is the point in disabling SOGo, then it is not a groupware anymore. Then you could better use something smaller like mailu or docker-mailserver.
