Email notification error - Illegal address

Issue:

I am in the process of testing the new flow and have created a scenario to test the Email Notification that is sent when the file does not exist and am having the below issue:

javax.mail.internet.AddressException: Illegal address in string `` ''
at javax.mail.internet.InternetAddress.<init>(InternetAddress.java:94)
at com.adeptia.indigo.services.notification.SendNotificationMail.sendMail(SendNotificationMail.java:154)
rethrown as
com.adeptia.indigo.utils.IndigoException: Illegal address
at com.adeptia.indigo.services.notification.SendNotificationMail.sendMail(SendNotificationMail.java:212)

 Cause:

There is an issue with the Mail Server Parameters configured here: “ Administer > Setup > Application Settings > Update System Properties > System”

Solution:

Disable the ssl and change the port to 25 in mail server parameters(Setup > Application Settings > Update System Properties > Systems)
