Redmine

I had set a group that has some users.
Now, to create a issue and assign this issue to the group, set due day as yesterday,
execute:

bundle exec rake redmine:send_reminders days=1 RAILS_ENV="production" 

get error:

E, [2022-08-03T10:19:27.602043 #152172] ERROR -- : Email delivery error: end of file reached

I tried use crontab to trigger reminder, today I got the message:

I thinks that means there has 39 issues over due day.

At the final, I set other issue over due day and assign to me only,
the email can send to me, and I saw the content has the last one and above issues.

Please hava a check. Thanks.
