Secure Interface Gateway - sending email

[KrzysztofSoczewka]

We tested the following code using Gmail SMTP. A 16-character Google App Password was generated and entered as Server_Password. However, the controller still does not send the email, function not return an error, but the email is not received.
VAR
sendMail : BOOL := FALSE;
sendMessage : Email_SendMessage;
res : Email_Errors;
END_VAR
We used:
SMTP server: smtp.gmail.com
Port: 587
Authentication: Auth_Login
TLS: TRUE
STARTTLS: TRUE
Password: Google App Password

The actual Google App Password should not be shared for security reasons.

Hello, looking at the settings you sent, I’d recommend checking two things:
TLS and STARTTLS:
Port 587: STARTTLS TRUE and TLS FALSE
Port 465: TLS TRUE and STARTTLS FALSE
Password:
The Google password must be entered without spaces to avoid errors.
If you continue to have problems even after making these changes, please share the program with me if possible so I can check it and help you.

Thank you for your help. The issue was caused by spaces in the password. After removing them, it works correctly.
