Best practise for self-hosted email server

MofoMooh

Cheers guys,

is there any best practise guide for a self-hosted email server?
If I do this with my providers IP a get a lot of problems (no correct reverse DNS entry, exposing my server, etc.).

Could a nano VPS with a well known provider as a relay SMTP help? Is there any guide (configuration of a smarthost, mailcows settings of the private server),

Thanks in advance.

MofoMooh Could a nano VPS with a well known provider as a relay SMTP help?

Whatever a “nano VPS” is. It must have at least 6 GB RAM as per minimum requirements.
And sure, a relay SMTP helps if you have not the possibility to set a reverse DNS entry and/or have no truly static IP.
In mailcow just configure it as “sender dependent transport”, and then configure each domain to use this transport.

Hi, there are some mailcow explanatory/installation videos on Youtube out there.
Also it is important to read the prerequisites and understand them before installing.
https://docs.mailcow.email/prerequisite/prerequisite-system/
As the videos (and other installation guides out there) are probably not up to date on some settings, please use only the official docs to install.

esackbauer Thanks for your answer, but I don’t need general guides but ones for the above mentioned case.
