So I just had a manager contact me because she was trying to help her new hire set up signatures in the Zimbra Collaboration Suite (we're running 5.0.23) and every time they create a message with the new hire's signature, horror of horrors, it prepends a pair of dashes! Good old fashioned .sig behavior where I come from, but they don't like it and want it turned off. Existing users don't seem to have this problem, they can include or not include a signature with the message and it doesn't add any dashes or asterisks or anything. Further, this new hire is also set up with Mail.app on her Mac Mini, and that doesn't include any kind of separation between message and signature either. But is there a way to make this "--" go away so they don't complain about having to delete it every time?
