-    1. Convert all line endings to \\\\r\\\\n (DOS line endings).
-    2. Encode all occurrences of "From " at the beginning of a line
-       to "From=20" in order to prevent other mail programs to replace
-       this with "> From" (to avoid MBox conflicts) and thus invalidate
-       the signature.
