Your problem
My problem is: My old email address is changed with New one but the Email contact replied cannot work. Page Hit is OK.

My Test as below

  1. Change the old email address to a new one.
  2. Reinstall Mautic and Change the Old Email address to a new one.
  3. Keep the old email address but change the Email Service Provider(SMTP and IMAP)
  4. Keep the old email address but change the Email Service Provider but use a New MySQL Database

I have no other solutions but want to use just one VPS.
So I have installed the other Mautic APP in the same VPS. Then two Mautic instances can work well not have issues.

Anybody can fix this Mautic bug?
