I am seeing an intermittent issue where emails are not being sent, and there is no output in the regular log to indicate why. 3 out of our last 12 builds failed to email. When I turned on email-ext debug logging I got the following output:

{noformat}

MessagingException message: IOException while sending message{noformat}

The only difference between a successful email sent and an email failure is that last line:

{code:java} MessagingException message: IOException while sending message{code}

I noticed a similar recent issue in a different email plugin:  https://issues.jenkins-ci.org/browse/JENKINS-53305 Since we cannot rely on an email notification, we had to implement a policy to closely watch builds to see if they fail.

Re: MessagingException message: IOException while sending message Do you happen to run in AWS EC2? We bumped into a similar issue which was a bit difficult to trace and in the end concluded that it was most likely AWS throttling traffic to port 25 https://aws.amazon.com/premiumsupport/knowledge-center/ec2-port-25-throttle/

Re: MessagingException message: IOException while sending message Are you willing to try a debug build that will give more information as to the cause of this issue?

Re: MessagingException message: IOException while sending message

Thanks for your response. We actually stopped seeing the issue after upgrading all of our components. I did not see any relevant information in the release notes for the upgraded version. Our working system has these components (among others) Jenkins Version: 2.164.2  email-ext-plugin version: 2.66 java.version: 1.8.0_144
