I have posted it on dev a long time ago. It has to do with the server OS and Outlook2003:

By definition you have to use local linefeed when you subit mails via sendmail (or Postfix) which is \n on Unix and used by mail() on Unix. But you have to use Internet line feed (always \r\n) when talking to a SMTP server directly which is what happens with mail() on Windows.

For some unknown reason Outlook2003 garbles the mail when you do it not as described. I think other clients simple ignore the extra linefeeds the unpatched TYPO3 produces, but Outlook2003 doesn't.
