The answer to this may be very simple, but by digging too deep I may just fail to see the obvious. The story so far: I am using Kmail as my email client, running exim (ticked the sendmail box, but put the path to exim rather than sendmail - this seems to work), installed spamassasing via apt-get. I understand that I need to specify spamassassin as the MDA. Is there a way to do this for kmail ? Thank you Bradut
