Fix path to look for handlers

src/common.lua

     -- Handle action if it's valid
     --
     local action = os.getenv("IMAPDOMO_ACTION")
-    local file = "handlers/" .. action .. ".lua"
+    local file = os.getenv("IMAPFILTER_HOME") .. "/handlers/" .. action .. ".lua"
     local valid = {
         newmail = true,
         rewind = true,

src/imapdomo.skel

     #
     # List recognized handlers
     #
-    find "$IMAPDOMO_HOME/handlers" -name "*.lua" -printf "%f\n" \
+    find "$CfgDir/handlers" -name "*.lua" -printf "%f\n" \
       | sed 's/.lua$//'
