 # acl condition and variables

-# It is rather difficult to properly test spf.  We use libspf2 to do the work, and it
-# does the DNS lookups, so we cannot intercept them in the testsuite's usual fashion
-# to provide values for testcases.
+# The 127.0.0.1 source addr seems to be a builtin in the spf library; no dns lookup is done.
+# HOSTIPV4 does get a series of lookups (see server debug output to verify that).
 #
-# For now just check that what should be working syntax does not cause us to fall over.
-# Be careful with envelope-domains used for testcases, as real DNS lookups will be done.
+# The libspf2 object stack is built with an exim-specific DNS lookup base object,
+# so the testsuite intercept to fakedns works.  Be careful of names and addresses
+# used, as nonhandled lookups are passed on to real DNS.
