Unable To Send Test Email In vSphere Data Protection 6.x

Once you configure email settings in VDP, the first thing we do is send a test email to verify the configuration is good. The test email content should be something like:

This email has been generated by VMware vSphere Data Protection to test your email report settings.

However, you might come across an issue, where the test email does not trigger and you will see the following error in the web client:

In the vdr-server.log you can notice the following:

2017-06-07 01:46:27,636 ERROR [http-nio-8543-exec-9]-email.EmailBase: On try 0to send the email, recieved a connection error from the external email server:Could not connect to SMTP host: email.vmware.com, port:

Use SMTP port 25 to fix this issue.
So in the configuration of mail settings, in the field for Outgoing mail server, specify
<your mail sever > : 25

Note that there is <space> before and after the :
Save the settings and now the test email should work.

I believe port 587 is block on Firewall.base for VDP and explicitly mentioning 25 resolves this, as SMTP 25 is open on VDP.
You can netstat -ano | grep 25 and netstat -ano | grep 587

Hope this helps!
