Use mailbox.org to send emails from Forgejo

To allow Forgejo to send emails using mailbox.org, you need to:

Create an email app-password from Settings. It only needs SMTP access, so you can disable IMAP.
Configure Forgejo using app.ini:

[mailer]
ENABLED   = true
FROM      = {{SMTP sender}}
PROTOCOL  = smtps
SMTP_ADDR = smtp.mailbox.org
SMTP_PORT = 465
USER      = {{SMTP username}}
PASSWD    = {{SMTP token}}

{{SMTP username}} is your main email address. {{SMTP token}} is the app-password you created earlier. {{SMTP sender}} can be any email if you have a catch-all address. If you don't have a catch-all address, I believe you can use any of your aliases, but I haven't tested it.
