We 're using RT since nearly 6 Months, but got a little bit of trouble
because of customers saying our answers via RT are without content.
This is caused by some webmail-provider not being able to display
MIME-encoded text correctly (yahoo is one of them…).
After googling and searching in the wiki I didn’t find a solution. Maybe
I used the wrong keywords or something else went wrong…
Is there a way to send plaintext mails instead of MIME encoded ones?
