BDAqua,
On 24 April the ISP finally wrote back, and seemed to suggest a problem didn't exist! Here's the text:
I can confirm that unfortunately we are unable to recreate the behaviour you are describing. We have sent a brand new test message and a reply to an existing message in the inbox (to a co-reply paypal address so will not cause any problems). Both of these messages are in the Sent Objects folder which is the expected behaviour.
You should be able to just move any messages from Inbox.Sent and Sent objects.Sent folders into the correct parent Sent objects folder and delete these unwanted sub folders.
If we can be of any further help with regard to this or any other matter, please do not hesitate to contact us.
I replied on 26 April:
Thanks for your message, and the testing that you've done.
I'm a non-technical person trying to understand the issue. Your answers to the following questions would be very helpful.
1) Could you please confirm that my Webmail account currently has two 'Sent' sub folders as well as a 'Sent objects' folder?
2) Is there an explanation why Webmail created these two sub folders since the connectivity issue of 2nd April? (I didn't create them).
3) Before the connectivity issue of 2 April, sent emails were all in one folder, 'Sent objects'. Since then sent mail has not appeared in the 'Sent objects' folder. Is there a reason for this?
4) Before the connectivity issue of 2 April, Webmail (online) and the Mail application (on my computer) were mirroring each other, which I understood was the point of an IMAP account. This doesn't seem to be the case now. Can you advise what can be done to revert to the structure that existed before 2 April? For instance, could any changes to the Webmail preferences or configuration help in this respect?
5) You've written: "You should be able to just move any messages from Inbox.Sent and Sent objects.Sent folders into the correct parent Sent objects folder and delete these unwanted sub folders." Could you please explain how I can do this? Are you saying I can do this online in my Webmail account?
Do you have any thoughts on what the ISP has said?
iHope
