I run Anonaddy on a oracle cloud server without issues. You'll need some SMTP relay service like smtp2go or mailjet of course. But other than that it works fine.

Port 25 is only blocked outbound. Recieving mail works fine on oracle cloud free tier servers.
It's probably best to still use a VPN or seedbox. But the chance that you get some nice mail is much lower because much more effort is required by the lawfirm. In order to get the IP addresses of people seeding the torrent they would first need an account and would get banned pretty quickly by not seeding or just snatching hundreds of torrents and not downloading them
I use docker-mailserver which is just one docker container running the basic services without the complexity of a webui an managing groupware
https://github.com/fnep/mtv_dl mtv_dl allows searching the Mediathekview database from the command line and download all videos that haven't already been downloaded and that fit the search. I use it to download new episodes from TV shows that I'm interested in
