For some reason all of my external emails (outside the firewall) were
appending HTML code to the end.To fix this (if you are running MS
Exchange):
1)LOGON to your MAIL server. 2) Run Exchange ADMN. 3) Go to the Internet
Mail Connector screen. 4) In the bottom Left corner there is a switch
HTML. Make sure this is off. It appears that it is talking about
attachments but it effects standard mail as well. I have left the MIME
switch ON.
