I’ve been using Virtualmin for a number of years in parallel to a Microsoft 365 Exchange service. I am thinking of dropping Exchange in favour of using a mail system within Virtualmin and the only thing stopping me right now is the lack of a secondary MX in Virtualmin GPL.
My Virtualmin installation currently hosts a small number of low traffic websites, MySQL databases and a few mailboxes. DNS is manually managed on Google Cloud so there is nothing complicated in my current hosted setup or in need of “advanced” features other than my desire to build a more resilient local mail service.
Aside from the ability to setup secondary mail servers, what other unique selling points does Pro have over GPL on installations like this?
