E-Mail Notifications fail after File Transfer

Current Situation :

• When a YADE File Transfer job is configured to send email notifications after file transfer, the notification fails with error reported in order log:
  • [sendMail]java.lang.Exception: error occurred on send: Cannot invoke "javax.mail.internet.MimeMessage.setFrom(javax.mail.Address)" because "this. Message" is null
• As a result, no email notification is sent but the File transfer operation becomes successful
• Please find the attached files for your reference.

Desired Behaviour :

• Notifications should be sent after file transfer when the mail configuration is valid.
