I went over it as someone new to it, to make some obvious-to-experts-but-not-me fixes. --- doc/doc-txt/experimental-spec.txt | 54 +++++++++++++++++++++++++++++++ 1 file changed, 54 insertions(+) diff --git a/doc/doc-txt/experimental-spec.txt b/doc/doc-txt/experimental-spec.txt index 0073b07af..74b14fe06 100644 --- a/doc/doc-txt/experimental-spec.txt +++ b/doc/doc-txt/experimental-spec.txt @@ -520,6 +520,60 @@ EXPERIMENTAL_SRS=yes in your Local/Makefile. +DCC Support +-------------------------------------------------------------- + +*) Building exim + +In order to build exim with DCC support add + +EXPERIMENTAL_DCC=yes + +to your Makefile.
