Even after successfully connecting to host I am getting the following error:

I am using javamail 1.5.5 jar. I took the code from github https://github.com/FoulerBenny/SampleProject/blob/master/src/main/java/com/genericLibraries/EmailAttachmentSender.java
My intent is to use SSL but first of all trying this way as SSL was taking too long to respond
