Thanks for pointing me in the right direction. I made an embarrassingly stupid screwup.

It's not coming from Outlook; I'm using Firefox on Ubuntu (the same machine). The code in footer.php creates text that goes in the cell of a table in index.html. Originally this was done using shtml files, but I was given php files that I was told to use instead for security reasons. I am under the impression that all I have to do is make the changes described in my original post, but it's not working.

I've set up a staging server with Ubuntu 14.04, Apache, PHP, and MySQL, and I'm having a configuration issue that I need to resolve. index.html uses a server side include. I was required to change the shtml file it references to a php file, but it's not working properly. When my webpage uses the code: <?php include ("footer.shtml"); ?> then the page loads correctly However, when I change it to: <?php include ("footer.php"); ?> then I instead see a message stating, "This attachment was removed because it contains data that could pose a security risk." I can't determine which configuration file I need to change, and what the change needs to be.
