Who can point Domains and set up Mailserver for me? All popular open source providers like:
Mailu
Docker mail server
wildduck.email
archivopteryx.org
www.dbmail.org
www.elasticinbox.com
mailcow
mailinabox.email
www.iredmail.org
www.hmailserver.com
are basically fine for me as long as its "free" and opensource... The main thing is that some basic admin tools are included, a basic webmail interface for users + multiple domains and users are supported - Which I think is possible for pretty much all on the list so just basic stuff without any extravagant stunts that's all!
Conditions:
Installation of a free mail server alignment using open source software and integration of the domains (5 in sum).
Set up of some basic admin-tools and a standard webmail interface for users.
It must be possible to add and delete domains and users relatively easily.
That is it...
