[exim] Help to debug "cannot parse spamd output"

    I’m running exam 4.8x on Fedora and FreeBSD.

    My spam assassin is running on my Fedora.  
    The other exam (on FreeBSD) use SA thru a stunnel and shout many times with «  spam acl condition: cannot parse spamd output ».

    When I checked the SA logs, it seems to work and send an answer, even on cases where the « cannot parse » message is written.

    Could you guide me to debug the situation ?

    Regards,

    Nicolas
