I've setup Postmaster to send system emails via Mandrill. Everything's working fine, but, all of the HTML tags are getting stripped out.
Here's a snip from the Message field, which is rendering nicely in Postmaster's preview pane:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>{hook:subject}</title>
<style type="text/css">
/* /\/\/\/\/\/\/\/\/ CLIENT-SPECIFIC STYLES /\/\/\/\/\/\/\/\/ */
#outlook a{padding:0;} /* Force Outlook to provide a "view in browser" message */
Here's the raw text of the email I'm getting:
From: (client name / email redacted)
To:
Date: Mon, 20 Jan 2014 15:28:54 -0600
Subject: Enclosed is your activation code
Enclosed is your activation code
/* /\/\/\/\/\/\/\/\/ CLIENT-SPECIFIC STYLES /\/\/\/\/\/\/\/\/ */
#outlook a{padding:0;} /* Force Outlook to provide a "view in browser" message */
The CSS rules are making it through, but, looks like a strip_tags() or something is wiping out the HTML.
There is a setting for "Plain Text Only" in the area for the Mandrill config, but, it is set to false.
Running EE 2.7.2 and Postmaster 1.4.4.
Other than setting up per this post, and selecting Mandrill as the mechanism, none of the default EE email settings have been touched.
Any thoughts appreciated; will followup ASAP.
Edit 1: Other Add-ons Interfering?
Here are the relevant (hopefully) columns from exp_extensions; this is happening during the new member registration process (not sure if it's also happening in other situations); the form is coming from Zoo Visitor, has a Snaptcha captcha, and the user is sent to a Custom System Messages managed page on success, so I suppose there's plenty of room for interference.

Edit 2: Custom System Messages
Custom System Messages is installed, but, it shouldn't be involved in this process; on a successful submission, Zoo Visitor is the mechanism directing the browser to a template.
{unwrap}tag issue, that there is a conflict, because Postmaster should not be doing either of these things. I plan on taking a look into detail today, but in the mean time take a look at your exp_extensions table and see if any of the hooks used in Postmaster are being used with another add-on.
