Anton you sent me message
But on the one.com website I see:
587 with STARTTLS (recommended)
Can you please reference the page where you got details?
as i said the ONE.COM says TLS I read in your post STARTTLS hence i looked into it and added to my last post
Please provide a link with "ONE.COM says TLS".
Thanks Anton for taking time to help

That's settings guide for Gmail. I'm not sure why you are following it. I believe you should be following this:

Anton ref, GMAIL. you were correct, i was using wrong port and settings, when i seen SMTP, I thought i was looking at the correct setup.
Thank you for your time and patience with me, Very much appreciated
In one comment you say that you need TLS. In another one STARTTLS. Those are two completely different things.
As for the error, it the same as before. Most likely you are using wrong credentials. I would recommend checking with your SMTP provider.
