I am running Laragon Live & Hmailserver Live with no problems at all right now
To anyone out there who wants there own Domain email server I suggest using hmailserver it's free for windows its very simple and easy to use and it uses almost next to nothing on cpu and ram.
Remember you get 100% privacy no spying on your emails unlike gmail and hotmail and the rest who spy on us all
Here are the videos that helped me and that will help and teach you all on how to setup a perfect email server alongside with Laragon webhosting on a windows operating system.
Just watch the first ---> 1, 2, 3, 4 <--- tutorial videos.... the tutorial even shows you how to setup dkim, ssl so that your all setup to receive and send emails for your website etc....
For a antivirus he's got videos on that as well but ...my personal oppion the best one to use i suggest go with SpamAssain video 6
under each video hes got them in parts 1,2,3,4,5,6 etc
