20+ Options for hosting our own mail server

Mailu

Mailu To be frank, this one I liked very much. It can be easy as to run 3 to 5 commands if you docker and docker-compose installed already. As you might have noticed, above link to mailu itself is pointing to the docs. Go get it. Github issues is a best place, if you are stuck at something Mailu Issues. From my personal experience and as per docs, atleast 2GB of RAM is needed for running this. If you are trying to run with 1GB system, ensure swap is enabled in your system with atleast 1GB or more. Kubernates based scaling is also documented in docs.

WildDuck uses a distributed database (sharded + replicated MongoDB) as a backend for storing all data, including emails. WildDuck tries to follow Gmail in product design. If there's a decision to be made then usually the answer is to do whatever Gmail has done. Gitrepo.
