oh yeah - but I don’t recommend anyone really self host an smtp server… many many issues right there especially as most isps block the ports required and the IP addresses are often blocked as well. Just use a service and don’t spam and all should be well (so don’t get sending newsletter emails all the time)
tailscale will tunnel through and you can set it to pass through https. Lots of different ways to achieve this, as long as you have control over the dns and are able to set https up it will work. This is why for me I still use cloudflare, you can even setup a subdomain through their tunnels and they act as a cdn. For example, I run a linkstack instance, send instance and much more
