Checkmk Werk 15686: Allow Links in HTML Emails

ID: 15686 Title: Allow Links in HTML Emails Component: Notifications Level: 1 Class: Bug fix Version: 2.3.0b1 With Werk #15069 escaping for the <tt>Insert HTML section between body and table</tt> section was introduced. Unfortunately links were not allowed anymore. This Werk removes the escaping for links. Links (<tt>a</tt>) are now allowed with the attributes <tt>href</tt> and <tt>target</tt>. The <tt>href</tt> needs to be either relative or when absolute must use one of the following URL schemas: <tt>http</tt>, <tt>https</tt>, <tt>mailto</tt>.
