K-9 Mail not sending copy of sent mail to Sent folder

[#1]

Hi Folks,

I recently replaced my old Samsung S5 with a new S22. This didn't come with Samsung's own email client and I didn't want to use Gmail so I installed K-9 Mail. This is mostly working ok, using IMAP with the same settings as the S5, but for some reason it won't save copies of sent mail in the Sent folder. All I've got are the messages that were transferred over by Samsung Smart Switch. I've looked in my Plusnet Webmail Sent folder and that's the same.

The box is checked in settings for sent mail to be uploaded to the Sent folder (see attached) but it just isn't doing it. I even tried unchecking the box, shutting down and rebooting the phone then re-checking it but to no avail. Has anyone come across this problem or have any ideas how to solve it?

The phone is running Android 13 if that's relevant.

Just to say I have now resolved the problem. In K-9 Mail settings for the account folders most were set to automatic. I set the Sent folder to Sent and it is now working OK.
