[Deploying Sakai] Outgoing Email Configuration Error

[Sri Kota]

Hello Folks,
I did the following:

Step 1: Stopped Tomact
Step 2: Removed the mailarchive-james directory under webapps
Step 3: Set smtp.enabled=true
Step 4: Set smtp at org.sakaiproject.email.api.EmailService=xyz.edu
Step 5: Set smtp.dns.1=x.x.x.x and smtp.dns.2=x.x.x.x
Step 6: Set smtp.port=25
Step 7: Set the following:
mail.support=xyz at domain.com
portal.error.email=xyz at domain.com
setup.request=xyz at domain.com
notifyNewUserEmail=true
Step 8: Start Tomcat

I get the following error:
