Mail Import Test Failed Errors

Problem

While configuring support department mail importing via POP, you see the following error:

The Mail Import test failed: cannot select INBOX, is this a valid transport?

You may also see this error in an email notification.

Solution

To fix this issue:

  1. Go to Configuration () > System Settings > Support Departments.
  2. Click Edit for the department.
  3. Change Port to 995.
  4. Click Save Changes.
