We’ve recently changed our mail servers an did a rebuild. E-mail is working just fine.
The only real changed we made (in app.yml) are changing the “adress” part (which is the smtp server) and the enable_starttls_auto setting from false to true.
After the rebuild sidekiq appears to be idle … it says so in the top left corner.
Any ideas what might have caused this, and how we can fix it?
