I am getting the following code on top of all email captured tickets:
<!<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">>
It is also adding numerous line breaks throughout emails that were never there to begin with, usually in place of spaces.
I assume it may have something to do with the most our client environments running Outlook 2000 SP3 (don't get me started on this!!). One of our exchange servers is running 2007 but I doubt that would improve the content of the emails being sent.
I am having a look at the code to see where it strips HTML out, just thought there may be a known solution or somewhere to look for the issue.
