<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">The stmp standard dictates that a header field is terminated by a new line. An empty line terminates the list of header fields.</p>

<p style=" margin-top:12px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Hi,<br /><br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">when I a log message with a double linebreak "A\n\nA" to SMTPAppender, the resulting Email is not formatted properly.<br /><br />The MIME parts are not parsed but are display as the message body. It looks like the double linebreak is written directly into the Subject-Header.<br /><br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">With a single linebreak I get the same problem in Gmail. In Outlook the email is formatted properly, only the subject is cut at the linebreak.<br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Could this be a bug in Logback?<br /></p>
