I'm a big fan of self-hosting, but it requires the right infrastructure. You need a robust virtualization solution like Proxmox, equipped with sufficient CPU cores and RAM. For instance, allocating 16GB of RAM shouldn't be an issue if your server has 128GB to share. In my experience, solutions like Mailcow, which involve multiple services and containers (such as SMTP, IMAP, Redis, SSO, webmail, Rspamd, etc.), work very well. I have extensive experience running these systems, performing backups, restoring data, and updating their ecosystems. Additionally, I've had a positive experience setting up and running a self-hosted Sentry instance with Docker for a project that spanned several years. However, this experience might be somewhat outdated, as it was a few years ago.
