SMTP Could not authenticate?

Hi, I’m new with CyberPanel and I’m trying to send emails using SMTP.

I can access Rainloop with my email account created at https://myIP:8090/email/createEmailAccount .

However, when I try send email by php application, with same user and password created, it didn’t work.

When i tried to create a SMTP Host on Cyberpanel, at page https://myIP:8090/emailMarketing/, just creates a “admin localhost 25”. After, when I try to create new SMTP Host, just loading smtp criaton and after, nothing is created. I don’t understand what happen.
