Well that is entirely your decision.

I agree that even in 4.10.2 it still has a lot of issues. I reported more than 
twenty bugs in about two weeks.

I see huge issues with filtering, race conditions with mail moving and 
deletion, a data loss bug with my CRM114 filter rules, huge resource usage in 
possible default setup for POP3 accounts and even some issues I didn´t yet 
report, like all mails disappearing from a message list view if I press Ctrl+J 
on *one* mail in it - luckily it appears after selecting a different folder and 
going back.

I think KDEPIM still needs lots of stability and robustness and correctness 
work starting from any bugs that may cause data loss. I think it also needs 
testing for data safety on moving, copying mails, deleting mails, filtering 
mails tons of mails, also when being put under load.

I can understand your thoughts. I thought along those lines as well.

While I found a way I can use KDEPIM-2 4.10.2 with some restriction like 
letting mails flowing into a special inbox to weed out spam manually and Ctrl+J 
filter the safely it seems. I wouldn´t trust it to move 10000 mails from one 
folder to another and things like that.

But frankly, I just don´t want to leave it. I used KDEPIM since August 2003, I 
just don´t want to move over all my PIM data, especially not the mail to 
something else. I like the GUI, I like the features, I like lots of little 
details.

I don´t think that the developers do not want to improve KDEPIM-2. They are 
trying hard. I do think its more a lack of time.

Thus I am prepared to live with some limitations like described above for a 
while. And I am willing to invest some time to isolate test cases that may 
lead to easier reproducability of issues. My current idea is to simply my 
reproducer for the mail loss issues I found with my CRM114 spam filter rules to 
using a separate user with those 5000 or 10000 script generated mails and use 
a bog standard configuration with just those 5 filter rules and an empty maildir 
from scratch.

When I have that test setup, I can move around mails, copy them, copy folder 
structures and see what works.

For me its also an issue with time. Testing and reducing bugs to easily 
reproducable isolated test cases seems to be challenging to me with such a 
complex software - necessarily complex at times. I would love to work with 
other users on this. Maybe share workload. Maybe a bug triaging day? However 
in my current setup, I think due to space constraints on my SSD its not easy 
to afford compiling KDEPIM from source.

But I think that is where we users can help. Trying to get to the bottom of 
bugs and find "to reproduce this, you do this with an empty user". Still even 
then a dev needs to have time to look into this.

I don´t know an easy answer or solution, but I think it still needs lots of 
work.

I appreciate that Laurent Montel and others do actually work on fixing bugs a 
lot these days, from what I can see in KDE Commit Digests, but I also fully 
understand that with those 20 bug reports I already added quite lot work 
already.

KDEPIM-1 at some time also had quite nasty bugs with index files, "no subject" 
mails and other stuff, that took devs quite some time to fix as well. But I 
fully understand, if a user in the current state of affairs does not trust it 
too much. I don´t trust it very much either. I leave 30 days of mails on the 
POP3 server for a reason and am very reluctant to enable automatic filtering 
which gave my move mails race conditions for example. And I have no motivation 
at all to enable the CRM114 spam filter rules, until I am confident that the 
one-byte sized file bug has been fixed for good. I also do not trust it too much 
100000 mails from one place to another and things like that. I did trust 
KMail-1 with that, although I made it in smaller pieces, cause KMail-1 would 
be blocked for ages otherwise. But whats important: It did complete the work 
and the result was proper.

Ciao,
