SMTP Authentication

Select the email authentication mode:

• Anonymous: The default selection. If your Exchange server is within your firewall, you would typically use this authentication mode.
• Basic: If you select Basic, you must supply a user name and password in the SMTP User and SMTP Password fields.
• NTLM: Non-standard authentication. This mode provides tighter security into your SMTP server.

For detailed information about email authentication, see the Microsoft documentation.
