[Typo3-dev] direct mail and html

[Pieter Jelle]

Hi all

I'm having a little trouble with the way direct mail handles outgoing 
html mails.
I want direct mail to send html mails, but I don't want it to attach all 
inline images and send them with the mail. I don't want direct mail to 
replace links with special redirect links either.
However, after having done some research, it does not seem possible to 
get direct mail to bypass the attaching and link replacing (or at least 
not in a configurable way). So, I'm planning to adapt direct mail to 
make skip those steps and send the mail with direct links to our server 
for images.
However, I have taken a look at the source, and can't seem to see how I 
can safely disable these functions. The file I've been looking in is
t3lib/class.t3lib_htmlmail.php .
Can anyone tell me if this is the file the actual work gets done in?
Can anyone give me any hints on where to start or how to disable these 
functions without breaking direct mail?

Thanks in advance!

Best regards
