E-Mails are cleared out from IMAP-folders after mailbox migration

Hi Ingo,
thank you for your advice.

Maybe, but this is the version OpenSuse ships for their distro 15.6, the 
OpenSuse development communitiy considers that version as stable. Do you think 
the data (emails) management system has undergone major changes from 23.08 to 
25.08?

That's what I did. In my Webmail interface I created a parallel tree 
structure, say instead of folder "ABC" I created a folder "ABC___ " (for each 
affected folder). Then in contact I copied the messages of the affected folders 
to their destination. This time the messages remained. They even remained when 
I moved them to their target destination (i.e. ABC___ -> ABC).

So the problem seems to be solved for the moment. Still I have a bad feeling, 
considering that E-Mails might vanish without actively deleting them. Some of 
the emails I have been keeping for more than fifteen years. I'd probably notice 
that they are gone not before I start searching for them. I think, I will make 
more frequent use of the vailable backup tools such as pimsettingexporter.

I have been using SuSE/OpenSuse over decades, since a friend persuaded me to 
give Linux a chance. As to their versions of applications philosophy, well, 
it's their philosophy and a lot of people put in much effort and time to 
provide us a stable desktop distribution, which is easy to work with. There 
are thousands of packages. To be honest, kdepim is the part which gives me 
most of the headaches among these.
