SMTP email failure

We have a simple custom UBE that checks for an error condition nightly and if it exists, sends an email using the Send Message system function. A new QA server (AS400) was created recently, which essentially was a copy of an existing server. Same setup, data, code, etc as our old server. However, when the email UBE executes the email doesn't get sent, an error is shown in the jde logs.

This works on our production server, and on our old QA Server. I'm not sure exactly what to check on the server to see what is missing. Any thoughts would be appreciated. See the error messages below.

Hi,

Can you ping SMTP.REMARKETINGSOLUTION.COM from your
server? Type it exactly as it is shown on your error.
If you can't, then you'd need to add a HOSTS entry

Sounds like your host entries. If this is not the problem check the JDE.ini file on the new AS400 server. Specifically the [JDEMAIL] section to be sure your mail server is defined.
