-    Pending an smtp library update, currently only email providers that work with STARTTLS will work with GoToSocial. STARTTLS is generally available over **port 587**.

 Note that if you don't set `Host`, then email sending via smtp will be disabled, and the other settings will be ignored. GoToSocial will still log (at trace level) emails that *would* have been sent if smtp was enabled.
 
-## When are emails sent?
+## Behavior
+
+### SSL
+
+GoToSocial requires your smtp server to present valid SSL certificates. Most of the big services like Mailgun do this anyway, but if you're running your own mail server without SSL for some reason, and you're trying to connect GoToSocial to it, it will not work.
+
+The exception to this requirement is if you're running your mail server (or bridge to a mail server) on `localhost`, in which case SSL certs are not required.
+
+### When are emails sent?
 
 Currently, emails are sent:
 
-- To the provided email address of a new user to request email confirmation when a new account is created via the sign up page or API.
-- To instance admins when a new account is created in this way.
+- To the provided email address of a new user to request email confirmation when a new account is created via the API.
 - To all active instance moderators + admins when a new moderation report is received. By default, recipients are Bcc'd, but you can change this behavior with the setting `smtp-disclose-recipients`.
 - To the creator of a report (on this instance) when the report is closed by a moderator.
 
-## HTML versus Plaintext
+### Can I test if my SMTP configuration is correct?
+
+Yes, you can use the API to send a test email to yourself. Check the API documentation for the `/api/v1/admin/email/test` endpoint.
+
+### HTML versus Plaintext
 
 Emails are sent in plaintext by default. At this point, there is no option to send emails in html, but this is something that might be added later if there's enough demand for it.
