Connect a custom SMTP server

Save the connection

1. Open Email delivery under Integrations.
2. Enter the SMTP server and port. Use STARTTLS on port 587 when supported, or SSL/TLS on port 465 when required by the provider.
3. Enter the SMTP username and password. Leave a stored password blank when editing other fields.
4. Enter the From address and choose the organization name, portal name, or a custom From name.
5. Select Save SMTP settings, then complete the security confirmation shown in the dialog.

Test and activate

1. Enter an address you can inspect and select Send test email. Testing does not require another security confirmation.
2. Confirm the message arrives, displays the expected From name, and passes the organization’s normal filtering.
3. Select Activate organization SMTP and confirm the sensitive activation change.

Choosing connection security

• STARTTLS upgrades a standard SMTP connection to TLS and is commonly used on port 587.
• SSL/TLS starts the connection inside TLS and is commonly used on port 465.
• None should be used only for an explicitly approved private relay; never send credentials over an unencrypted internet connection.
