These appear to be Lucee errors and have nothing to do with the email service. Can you serve up any CFML pages?

With Railo, similar error. All other Railo apps work just fine. Possibly more on AWS side.

Can you post some code and tell us what mail settings you are using? What version of Lucee? Are you using SES @ AWS? The more info, the better. We are currently using these services and are having zero issues with the latest version of Lucee.

I then switch to gmail stmp server, log indicates error as well but later email were delivered on Railo, weird.
