My father has recently passed away in an unexpected manner. He managed all our family domain email servers using a combination of postfix, roundcube etc. I have managed to gain access to his server however I have no experience with any of these tools.
mailcow seems to be an easier solution to setup however I would like help for migrating everything to a new server while keeping all past emails etc and aliases and such with all the directions people chose.
If anyone would be willing to help I would be very grateful
