Mail Server with STARTTLS Failed

Mail Server with STARTTLS Failed

My mail server use STARTTLS for connection security. I use eventloganalyzer_7.2, but i dont have success in order to send an email.
I have not access to Internet from my ELA server. So gmail alternatives is impossible.
I capture the packets between ELA and mail server and i got SMTP Error Code 502

Please anything about it, let me know

Regards,
Miguel Esnard
