Hi, OLEMacro plugin has been renamed to OLEVBMacro both in trunk and in 3.4 tree. If you have enabled this plugin in v343.pre you should modify your configuration files to cope with this change.
this one-liner will do the trick: # sed -i 's/OLEMacro/OLEVBMacro/g' /etc/mail/spamassassin/v343.pre Giovanni
