Should be easy, right?  My DEV environment is working just find and sending out alerts via email, however my TST and PRD environments are showing "ERROR #6070: SMTP Send failed" on the Ens.Alert email operation.  Same configuration settings on the operation, same SMTP server being addressed (I confirmed that I can ping the mail server from DEV, TST, and PRD boxes) and same port#.  I turned on "Log Trace Events" but don't see anything additional in the logs. Am I missing something?     

Let me know if you have any thoughts.

Thanks,

Hunter
