Outlook conditional tags are removed in mailer

[ictbeheer]

Problem

During processing of the mailer Outlook conditional tags (such as <!--[if mso]> are removed which messes up the layout.
This is caused by the following regex:

Caldera-Forms/classes/save.php

Line 259 in be69a86

preg_match_all( "/\[if (.+?)?\](?:(.+?)?\[\/if\])?/", $mail['message'], $hasifs );

Solution

Make the regex more restrictive so Outlook conditional tags are not replaced.
