[Koha] Notice Email send error

[Ms. Naveen Ali]

Dear All, 

I am trying to send email notices; 

Using KOHA 21.11 and have configured the SMTP servers using the option in the Administration Module 

I have tried Gmail as well as our university email server hosted on zimbra; and both give error 

"Unhandled email failure, check the logs for further details" 

Where do look for these logs to identify the problem? 

Gmail Settings. 
Host: smtp.gmail.com 
Port: 587 
Timeout:120s 
SSL: SSL 
Authentication: Yes (My gmail emal address and password) 


With best regards, 

Naveen Ali
