The problem does still appear in Akonadi + KMail 15.08.1.

Thank you Telmo and all the commenters for your report and comments.

It is about a version of KMail which uses Nepomuk and is unmaintained. Thus
closing. If you still see performance issues please open new reports. But
please follow the following guide lines to avoid unnecessary work for the
developers:

- Ideally test with KDEPIM and Akonadi 15.08. It contains some performance
improvements like the binary protocol.

- Otherwise at least use KDEPIM 4.14.10 and newest Akonadi 1.13 you can get as
it already contains some performance improvements.

- If you can wait, please retest with KDEPIM and Akonadi 15.12 once they become
available for you. Akonadi 15.12 will contain *massive* performance
improvements implemented by Dan due to new database indexes, optimized queries
and leveled file_db directory. All of these are in master already, so if you
dare use kdesrc-build to compile KF5, kdepim and kdepim-runtime. I am using
this currently and it basically moves the bottleneck to KMail (displaying
message list
of huge folder). It is a *huge* improvement. And also Volker and Dan work to
improve
message list display speed as well.

- Please also always report only one issue per report and check for duplicates
before
reporting.

Thank you and greetings from KDE Randa Meetings,
Martin

I just have the duplication issue again. The message reads. (translated from
german):
-
The UID of the newly created message on the server can not be determined
-

The source of the mails are all equal except the following detail:

Every duplicate has the following lines preceding the original header:
-
X-Spam-Checker-Version: SpamAssassin 3.3.2 (2011-06-06) on sed-notebook.havi.de
X-Spam-Status: No, score=0.0 required=5.0 tests=HTML_MESSAGE,T_DKIM_INVALID
autolearn=ham version=3.3.2
X-Virus-Flag: no
X-Virus-Flag: no
-
And every further copy has one additional line reading X-Virus-Flag: no

Further the Header items have no line breaks any more. As an example the field
Content-Type changes from
-
Content-Type: multipart/alternative;
boundary0431793831243792098==
-
to
-
Content-Type: multipart/alternative;
boundary0431793831243792098==
-

I have no idea whether this is important. But I shall add that I used both
ClamAV and SpamAssassin with Thunderbird, too, and did not see that problem.

(Thunderbird has other very serious problems, so it is no option any more.)

Sorry for the double post, but I didn't see this before and want to give as
much detail as possible.

There is another change in the header of the duplicates. The first duplicate
reads as above, but all that follow have a different second line:

-
X-Spam-Status: No, score=0.0 required=5.0 tests=HTML_MESSAGE,T_DKIM_INVALID
autolearn=unavailable version=3.3.2
-

The change is from autolearn=ham to autolearn=unavailable.

I can confirm this when using an old IMAP server at work. POP3 works
flawlessly. But When a new message arrives on the IMAP server, it is received
once, and then again every few seconds. all accompanied by a system
notification:


save failed. server replied BAD Error AXXX in IMAP command UID: invalid
arguments

with XXX raised by one with each duplication.

After some iterations the senders mail adress gets lost in the duplicates, then
later the sending date.

To stop this I have to switch kmail to offline, log in via web interface (Horde
Mail) and manually delete all but the original mail from the server.

Used here is KDE-4.9.3.

Btw.: I am the only one around here using kmail, and I am the only one having
this problem. When I use the very same account with Thunderbird, no duplication
ever happens.

I have the same problem with two IMAP servers (imap.bbox.fr and
mail.math.univ-toulouse.fr). I do not use davmail. Only new messages are
duplicates (up to 2000 times), not only in kmail, but also on the servers.
I use Kmail 4.9.2 and akonadi-server 1.8.0 from kubuntu 12.10.

I have the same problem with Gmail (DavServer). But only the new messages are
duplicating (the program is creating an empty message duplicate from a normal
message).
