In Email, Image (img) Source (src) Tags are rewritten as relative links. How to fix?

Question

I'm working on sending out an html based email, and every time it sends the image src tags and some of the anchor href tags are modified to be relative url's.

Update 2: This is happening between when the body of the email is generated and sent and when it arrives in my inbox.

Update: I am using Postfix on a LAMPP server. In addition, I am using Zend_Mail to send the emails out.

For example, I have a link:

src="http://www.furnituretrainingcompany.com/images/email/highpoint_2009_04/header.jpg"

And it gets rewritten as:

src="../../../../images/email/highpoint_2009_04/header.jpg"

What can cause this to occur and how is it corrected?

Answer 1

As it turned out, even though when I copied and pasted the content into the application the necessary DOCTYPE, html, and body tags were in place, TinyMCE was stripping those tags. Which explains why the output only showed the content within the body tag.

I was able to fix the url rewrite problem by ensuring that the DOCTYPE, html and body tags were actually all in place.

And I fixed TinyMCE by adding in the fullpage plugin so that it no longer strips those tags from the input.
