I do not have recorded time stamps initially. But I looked now:

All timestamps are from yesterday afternoon and evening and correlate to my 
postings where I reported the issue here on this list.

So I think, I am good to go for know.


Please elaborate what you see. Do you use filtering rules that pipe mails 
through an executable, like I did? 


I somewhat reached a stable state for now it seems. I just switched all the 
filters to filter for incoming mails from POP3 account only, which basically 
appears to have them not working at all (reported, see reply to Andras). To 
easily Ctrl+A and Ctrl+J them after I deleted the spam mails - cause, well, I 
disabled my spam filter rules - I let new mails flow into a folder called like 
"aaUnfiltered".

This will work for now.

I am ready to cope with some inconveniences for a while.

But I will carefully monitor for data loss. I do not accept data losses.


I have set POP3 resource to keep mails on POP3 server 30 days. So I will have 
some time to see whether I can get to a working for me setup. But since 
rolling back to KDEPIM-1 may become more difficult with time, the next two weeks 
will be most important for me.

Well an easy way to roleback could be to just give it that new maildir from 
KDEPIM-2 after I restored those 33 mails from the server. It has still the old 
index files in it. But then KMail-1 would take ages to update them - I had this 
during first rollback. So it might be easier to just rollback to a synchron 
state of maildir and KMail-1 configuration, cause then KMail 1 does not seem to 
trigger a rescan of index files. And then have it redownload everything from 
the server.

Well, I do hope another downgrade won´t be necessary.

Actually I remember having coped with mail loss or at least disappear from 
view problems back in KDEPIM-1 times as well. Index file handling. Something 
KMail 1 took index file contents for granted and just didn´t display mails that 
were not in index file. But with KDEPIM 4.4.11 I have been really satisfied with 
stability and robostness regarding mail data storage.
