Dear all,
I have the following error. I use outlook 2007 to get mail from zimbra server and i setup a signature with an image linked from URL on that. But when i use outlook to send email to myself, in outlook the signature display ok, but in web interface, the email show 2 attachment file, one Unknow file with rich text format and one picture that i insert (link to file) in signature.

Anybody have advice? Any feedback is so appreciate. Thanks!
