can webform send email in html format?

You just have to delete [ and ].
For example, if your node id is 6, the code should be :
phptemplate_webform_mail_message_6

Hi everybody,

I've been working on the e-mail formatting for a while now and everything is coming into place.
Only problem is that the links I receive in my e-mail aren't clickable after adding the code in my template.php file
I added as suggested, the following:

function phptemplate_webform_mail_headers($form_values, $node, $sid, $cid) {
$headers = array(
'Content-Type' => 'text/html; charset=UTF-8; format=flowed; delsp=yes',
'X-Mailer' => 'Drupal Webform (PHP/'. phpversion() .')',
);
return $headers;
}

Any ideas on how to get the links, for example; "the result can be viewed at..." or "links of images" clickable?

Thnx in advance.

I added this function, and it looks like I am getting html, but there are no line breaks. Here is what the output looks like:

If you're using the SMTP module remember to enable 'Allow to send e-mails formated as Html'

with webform 6.3 the function has changed to:

function MYTHEME_webform_mail_headers($node, $submission, $email) {
  $headers = array(
    'Content-Type'  => 'text/html; charset=UTF-8; format=flowed; delsp=yes',
    'X-Mailer' => 'Drupal Webform (PHP/' . phpversion() . ')',
  );
  return $headers;
}

although not necessary now with HTML format available within webform 6.3, it could still be used to override text format

@brantwynn
Its working with 6.22 and webform 6.x-3.11. After clearing cache just edit your e-mail and put code in <body>your code, inclunding Tokens </body>

See Webform module folder's THEME.txt file there was a template suggestions to set headers per Webform (node ID) if I can remember.
