Error occurs while sending email via AWS SES SMTP

Hi,

I am using version 8.0 and I am trying to send an email via AWS SES SMTP and I have provided all the details required for it. "Transport Security" is not provided. And we are using "25" port. I have referred below link

but I could not find the mentioned configuration parameters in this version. Can you please suggest how to allow certificates to be self signed. Thank you.
