No provider for smtp exception using AWS SES


I'm all of a sudden getting the following errors when trying to send email. Some emails send fine, others don't. I have over 1K emails stacked up in my mail tasks

My email config in Lucee is:

When I try to send a test message for this smtp server, Lucee indicates that the task succeeds with the message: "Test mail has been sent successfully using [ ]." but the message does not get delivered. The undelivered mail does show up in tasks, and fails again when I try to execute the task manually.

An aside, the problem very specifically started on Oct. 2, which may have coincided with my last Lucee update, but I cannot recall the exact date that I updated so I cannot confirm that the update was the problem. Is there a way for me to determine the last time Lucee was updated to determine if the update caused the problem?

positive feedback on the mailing list, this has fixed the problems for many people

we should backport this to 5.3.7 and do a new release, especially as the installer hasn’t been built yet

please give the latest Lucee version a try, if the email issues remain

just a quick heads up, the build failed so the isn’t available for testing yet
