Email sending failed

Bug
1

For installing discourse with official guideline and env, with many days I encountered email failure.

Latest version upgraded, and failure logs now is shown. The commit - FIX: don’t create an EmailLog when we can’t send a digest

Now I can see the following error, and it seems it is not due to smtp server error.

Log error is:

Job exception: end of file reached

The backtrace is:

I have also been getting this error lately … first I see the following in /admin:

Some problems have been found with your installation of Discourse:
Email polling has generated an error in the past 24 hours. Look at the logs for more details.

I actually don’t think the above message is related, but the errors seems to be related to Jobs::UserEmail and Jobs::NotifyMailingListSubscribers.

Same error here @downey: end of file reached is what the JSON returns.

Stack trace the same as @javenfang.
