I have a setup with Mac and Windows clients. The Mac users use Apple Mail and all users have an HTML signature with images. When a Mac user replies to an email the text from the initial message becomes an attachment with the name:
untitled attachment001.html and the image from the signature becomes an attachment with the name:
Can this behaviour be avoided? How can I preserve the original email and signature?
I have managed the following. I discovered that it was due to the malformed signature. So I created a .webarchive file that contains the signature as I want to be. The signature appears correctly at both the file and the apple mail signature editor. But when I open to write a new mail only the borders of the signature image appear and there is an '?' inside the borders. What does this mean?
