Hi there,
I was intrigued by the idea of self-hosting my social media accounts, but was more or less a complete noob with all things hosting.
However, with the help of the community here (and quite a few hours spent on it) I finally have a working setup! Mastodon, Matrix, Lemmy, Nextcloud all self-hosted behind Nginx Proxy Manager.
Google can find a lot of answers, but sometimes some really specific input is needed - which you guys have provided over the last couple of weeks - so I just wanna say thank you for that!
I use Synapse as Matrix server and Element as client. It doesn't need port 25 (8008 and 8448 are needed in my setup).
On Lemmy and Mastodon I configured outgoing mail using smtp via my existing mail hoster, so I don't send mail from my own server. Also, all googling I did said to stay away from selfhosting email, as it is a hassle not to be immediately blocked as a spam mail server ..
So yes I got synapse installed and I use element as a client but when I tried to register an account it wants to send me an email from my own server and since port 25 is blocked.
