PHP Mail

PHP Mail leaves WordPress’s own mail delivery in place — the same mail() function it would use without BooleanSMTP installed — and only applies the connection’s From address and From name. It needs no host, API key, or password, so there’s nothing to gather before you add it.

Caution

PHP Mail is often filtered as spam, because it sends directly from your web server instead of through an authenticated provider. Use it for local testing or as a last-resort fallback, not as your primary connection.

Add the connection

1. In your WordPress admin sidebar, go to BooleanSMTP → Mailers.
2. Click Add Connection and choose PHP Mail.
3. Under Sender Settings, fill in From Email (on your site’s own domain) and From Name.
4. Click Register Connection.

Send a test email

Use Test Email in the sidebar to confirm the connection works — see Send a test email for the steps. A successful test only confirms your server handed the message off, not that it reached the inbox.

Common errors

If the test fails, your host has likely disabled the server’s local mail function — there’s no setting on this connection to fix that. Use a real provider connection instead.
