I have been doing some work on an mailing system and sent a test e-mail to myself. This had an html body and a paragraph for which the font was declared as itc zapf chancery , cursive. I know this is not a good choice but it was only a test. When displaying the html message in thunderbird, Zapf Chancery was not used and the paragraph displayed in some other font. If I go into preferences -> composition, I can display a list of fonts that includes itc zapf chancery. Thunderbird displays the html page without problems.
Does anyone else have this problem or is there a magic hidden option that I have not found?
I normally set thunderbird to display messages as plain text.
