I have managed to have a working mailcow server runing, behind a nginx reverse proxy (I already had some services on the same server)
For the mailcow server to be reachable on 80 and 443 I put a .conf file for my nginx reverse proxy to redirect to the mailcow server for request on mail.domain.org.
But I can’t get any client to connect to the server (except SOGo, and Exchange-based Android clients). I was wondering if there is a port redirection for 993, 587, 143, etc. to add in the nginx .conf.d folder ?
My goal is to use the nextcloud web client, but I can’t manage to auth.
Where sould I start looking for clues ? Didn’t found much in devcot and postfix logs.
