To allow Forgejo to send emails using Proton, you need to:

Create an SMTP token in Proton from settings.
Configure Forgejo using app.ini:

[mailer]
ENABLED        = true
FROM           = {{SMTP username}}
PROTOCOL       = smtp+starttls 
SMTP_ADDR      = smtp.protonmail.ch
SMTP_PORT      = 587
USER           = {{SMTP username}}
PASSWD         = {{SMTP token}}

Where {{SMTP username}} and {{SMTP token}} should be copied from Proton.
