Hello Zhang,
I found an error when clicking on "View or hide mail body and header" for any email in quarantine. The error is:

Error: TypeError("can't concat int to bytes",) 

The error in log is:

Oct 29 12:28:29 mail iredadmin: GET /iredadmin/activities/quarantined 200 442038 "https://mail.domain.net/iredadmin/dashboard"
Oct 29 12:28:33 mail iredadmin: GET /iredadmin/activities/quarantined/raw/usSDt7ns8aix 303 342 "https://mail.domain.net/iredadmin/activities/quarantined"
Oct 29 12:28:34 mail iredadmin: GET /iredadmin/activities/quarantined?msg=TypeError%28%22can%27t%20concat%20int%20to%20bytes%22%2C%29 200 442311 "https://mail.domain.net/iredadmin/activities/quarantined"

I added a screenshot of the panel. For every click on every row on "View or hide mail body and header" it opens another page inside the row.

What could be the solution here?
Thank you for your help!

Tom
