[Typo3] css and direct mail

[Pieter Jelle]

Hello all

I'm having a little trouble sending a newsletter with Direct Mail.

The newsletter uses inline CSS, and has a few references to image files 
from CSS, like for instance :

ul li { background: url("images/arrow.gif") top left no-repeat; }

Direct Mail finds all references to images in a HTML mail, attaches the 
images and changes the references in the source to refer to the attached 
images and sends the mail. However, this doesn't seem to work for the 
images referred to in CSS, as they don't show in the mail (while they do 
work when opening the newsletter in the browser by its page ID).

My question is : can Direct Mail be told to leave the source untouched 
and fetch all images directly from the server (like with dmailerping=1, 
but that doesn't work with CSS) or can I fix Direct Mail to handle these 
references correctly? If so, where? I have already tested a few things 
in t3lib/class.t3lib_htmlmail.php , but that doesn't seem to have any 
effect.

Any help will be greatly appreciated!

Best regards
