Testing SMTP

[djyde]

I implemented SMTP for self-host service. But it doesn't work well when I tested it with Gmail. I don't have time to test this feature yet. If someone is interested in it, feel free to contribute.

I tested with a QQ exmail and it works smoothly. Gmail is similar but has a stricter access policy: https://nodemailer.com/usage/using-gmail/. TLDR; users should either allow the "less secure apps" to access or set up an app-specific auth with 2FA enabled.

I think we should expose the interface for custom Email first and instruct users how to correctly set up a (user, pass) pair for this kind of mail service.

UPDATE: I set up an app-specific password for Gmail and it works.

Wow that's surprised me that the code I never test works fine 🤣

I thought about instead of passing these env vars about SMTP, we could provide a settings panel for SMTP settings and save theme in the database. It's more user-friendly and we could provide more built-in preset later.
