I am having some new issues with email sending which have started in the last 4 days. Not sure whether best to continue this thread or start a new one, but for now will continue this one.
I had recently done a full site update from the command line around the time this issue occurred.
- No users are being sent any notification emails about activity on the site.
- SMTP sending seems to work fine, an email deliverability test worked instantly.
- Sidekiq shows thousands of enqueued jobs which are retried regularly but are failing consistently. (7000+ jobs enqueued)
- Logs show one very prominent and numerous error Job exception:
UserDestroyer::PostsExistError- I have looked this up on Meta but nobody else having similar issues since at least 2017 when the last topic mentioned it. (9000+ errors all in the last 4 days)
