Error in sending email from STM32H7 based processor board using SMTP client APIs in LWIP TCP/IP stack.

Hi, I am trying to create an SMTP client application using LWIP to send/receive emails from my STM32H7 based processor board, I am using smtp_send_mail() to send emails, although this functions returns ERR_OK, i couldn't monitor the emails being sent. 

Please let me know, is there anything i am missing.

This issue has been resolved, the error was due to incorrect SMTP host address.
