Email Setup Giving errors

Using Jenkins
1

Hello,

I have Jenkins version 2.440.2.

I’m trying to set up the email notification under system configuration.

I scroll down to the E-mail Notification , under SMTP server I put in smtp.comcast.net
I click on the advanced and check off use SMTP Auth, I put in a valid user id and password

I scroll down and check use SSL and set the port to 587, and set the reply to a valid email address, I then scroll down and do a test configuration and put in a valid email address.

When I test it fails to connect and send the email Below is the error I get
any ideas what I’m doing wrong ?

I have a Project that is using Powershell to accomplish the same at that works with no issues. I’m trying to set up the email so I can get alerts when the jobs fail
