Hello,

how can the spam-markup be removed from mails that have first being marked as SPAM automatically but are actually no spam and afterwards manually marked as Ham?
Can this be achieved by creating an additional custom filter rule in kmail, perhaps by piping the Ham mails through a special spamassassin command?

I assume, that this post https://github.com/akhuettel/kdepim-noakonadi/blob/master/kmail/antispamwizard.h handles the same topic, at least in line 192 and 193. Unfortunately my understanding is to poor to try the next steps by my own.

Environment:
OpenSUSE Leap 42.1 (x86_64)
KDE Framework 5 5.16.0
QT 5.5.1-4.1
kmail 5.0.3

That content is, IIRC, added by the spam filtering daemon and not by KMail, if I understand correctly. Are you referring to the text like "Spam software, running on...."?
