The filter log says (localized in german. if you could provide me information how to get the english output i'll post it): [19:49:29] Filterung beginnt bei Nachricht „Re: xxx“ von „xxx “ um „Freitag, 15. Januar 2016 19:45:47 UTC+01:00“ : [19:49:29] Filterregeln werden geprüft: (auf alle Nachrichten zutreffen) "<size>" <greater> "0" [19:49:29] Filterregeln wurden angewandt. [19:49:29] Filteraktion anwenden: Durch Programm leiten "spamassassin -L" [19:49:31] Filterregeln werden geprüft: (alle folgenden Bedingungen müssen zutreffen) "X-Spam-Flag" <equals> "YES" [19:49:31] 1 = "X-Spam-Flag" <equals> "YES" (YES) [19:49:31] Filterregeln wurden angewandt. [19:49:31] Filteraktion anwenden: In Ordner verschieben "Lokale Ordner/Papierkorb" [19:49:31] Filteraktion anwenden: Markieren als "Gelesen" The problem: [19:49:31] 1 = "X-Spam-Flag" <equals> "YES" (YES) However, *there is no X-Spam-Flag header the mail*. It seems as if the mail has not been touched by spamassassin at all. If I send the mail manually through spamassassin it is recognized as ham. The problem started with KF5. Reproducible: Sometimes Steps to Reproduce: receive emails. from time to time emails are apperently not processed by spamassassin, but marked as spam. Actual Results: the mail is marked as spam Expected Results: processing by spamassassin and correct header-filter-result behaviour. I've lost emails (and was asked why I did not respond), so I set the severity to critical. 1571026 1 tom-kde.bugs 2016-01-21 08:51:39 +0000 I changed the spamassassin ruleset to use "spamc" together with the daemonized version of spamassassin. What a performance boost! The time to scan one mail decreased from >10s to <1s. Maybe this fixes the problem, too, that mails are not processed at all (maybe because of a timeout?) However, kmail should not sort out mails where no spamassassin header is set at all. 1571465 2 tom-kde.bugs 2016-01-23 09:05:32 +0000 The problem is still present, however now there a logs.

(OK) The problem: - The incoming mail was not empty. It is a normal email. - Obviously kmail sends an empty file through spamassassin/spamc. - The empty file is recognized as spam. - Spamassassin generates its report, and kmail uses that X-Spam-Flag header for further filtering. Interesting fact: The mail is not replaced with spamassassins report. It stays untouched, but is moved to trash. So it seems as if the "pipe this email through a program" filter does not work reliably. Maybe a race condition? 1571478 4 tom-kde.bugs 2016-01-23 09:41:06 +0000 maybe related: https://bugs.kde.org/show_bug.cgi?id=255388 2163256 5 justin.zobel 2022-10-19 22:11:05 +0000 Thank you for reporting this bug in KDE software.
