I’ve modified mailing-list plugin.
– Added CATEGORY for article substitution
– Added “(This is the text version of the original post)”
 for the text version
– Adjusted “\r\n” characters to make sync. work without problems

  - When sending with “text/html”, there will be no context
  - It cannot handle “\n” properly, but “\r\n” is fine
– Blogger:
  - When there are “\r\n\r\n” in the context,
   or using “multipart/alternative”,
   the article will not be accepted by Blogger.

End of test.
