Description

When sending a multi-part message in MIME format, class.t3lib_htmlmail.php outputs an additional semicolon on the Content-Type header definition which is interpreted as a violation by antispam solutions such as MailScanner as it detects a null header. This leads to the message being quarantined.

Should have been fixed according to bug 9523 (http://bugs.typo3.org/view.php?id=9523) but is still present in 4.2.8 (lines 556 and 580) and 4.3.SVN rev.5574 (line 568).
