I'm going to start off but saying I know that self-hosting email can be a bad idea. That being said, I'm trying to de-googlfy my life and would like to experiment.

I have a VPS and a domain that doesn't get used for much at the moment. I'd like to try configuring a full mail suite on that domain and see if I can make it work. I've been looking into the various options on this list and was hoping for some feed back on options that people have used. If this works out it would be fairly low volume.

Ideally I'd like a full solution that includes web administration if at all possible. I think I'm leaning towards mailcow but it might be overkill.

I'd appreciate any input on what has or hasn't worked for people. Thanks.
