Since I updated virtualmin the last time (about 2 weeks ago) I can't set an auto reply message anymore. I'm managing 2 servers. The feature worked on both perfectly before and now it doesn't.
How to reproduce the error: - Go to "Edit Mail and FTP Users" - Click on a specific user - Choose "Mail forwarding settings" - Enter a text (just any text will do) in the "Send automatic reply" textfield - Click on the "Save" button
--> Errormessage: Failed to save mailbox : Unknown file mode >
I already checked the logs etc.
EDIT: I just found out that it works when setting the autoreply in usermin.
