Emails from website not working

Hi there

I really need help with one mail issue and would appreciate it a lot 🙂
I’m using plugin WP EASY SMTP, it is set up with the help form mail provider so I assume there shouldn’t be an issue.
However, no woocommerce emails or contact form emails are being sent.
This is what I found in logs:

  • “Mailer: Other SMTP
    PHPMailer was able to connect to SMTP server but failed while trying to send an email.”
  • “Mailer: Other SMTP
    SMTP Error: The following recipients failed:__________
    Sender address rejected: not owned by user”

Any suggestions?
Many thanks!
