Hi Vinz,

You need to adjust the allowed tags in the HTML::Scrubber object by adding a
Web_Local.pm:

https://www.bestpractical.com/docs/rt/4.2/RT/Interface/Web.html

Here is what I am using because I wanted to allow the tables to have colors:

----------------
package HTML::Mason::Commands;
# Let tables through
push @SCRUBBER_ALLOWED_TAGS, qw(TABLE THEAD TBODY TFOOT TR TD TH);
# Allow bgcolor to be set
$SCRUBBER_ALLOWED_ATTRIBUTES{bgcolor} = '^\s*\#[a-fA-F0-9]{3,6}\s*';
1;
----------------

Make sure to set the option in your RT_SiteConfig.pm

Set($TrustHTMLAttachments, 1);

I think that is all I needed to do. Then restart after clearing your Mason
cache.
