Oups, I've triggered the bug.... In fact (if this mail is also passed trough LMTP / SMTP Delivery on your mail server, the <<<EOT ... EOT; Section must have ONE dot on the second line and the <<<EOS ... EOS; Section must have TWO dots on the second line for data escaping.
(this bug only triggers when using {L,S}MTP Delivery).
BTW, the \n => \r\n Bug does not seems to be fixed or it is fixed
somewhere else.
