[Koha] SMTP configuration error

[Ms. Naveen Ali]

Dear All, 

I am trying to setup SMTP to send email notices; 

Using KOHA 21.11 and have configured the SMTP servers using the option in the Administration Module 
I have configured Gmail SMTP with the following information 
Host: smtp.gmail.com Port: 587 
Timeout:120s SSL: SSL 
Authentication: Yes (My gmail email address and password) 

I am receiving failed email status with "Unhandled email failure, check the logs for further details" 

Looking into mailing list threads, i tried running the process_message_queue.pl manually and got the following error 

library at KOHA:/usr/share/koha/bin/cronjobs$ ./process_message_queue.pl 
unable to locate Koha configuration file koha-conf.xml at /usr/share/koha/lib/C4/Context.pm line 170.

I tried updating the the /usr/share/koha/lib/C4/Context.pm file with the path /etc/koha/sites/library/koha-conf.xml but no success. How do I resolve this issue?? 

With thanks and best regards,
