What is the correct SMTP for Gmail?

Could you please clarify what you mean by "the correct SMTP for Gmail"? Are you referring to the Simple Mail Transfer Protocol (SMTP) settings that are required to send emails using Gmail as your outgoing mail server? If so, the SMTP settings for Gmail typically include the server address smtp.gmail.com, the port number 465 or 587 (depending on whether you're using SSL or TLS encryption), and the need to authenticate with your Gmail username and password. However, it's important to note that Gmail's SMTP settings may vary depending on the specific application or device you're using to send emails. Additionally, Gmail may require you to enable less secure apps access or use an app password if you're trying to connect to your Gmail account from a third-party application.
