zimbra does not show mail to them with HTML content

I only see code HTML... this situation begining when I did upgrade from zimbra 4.5 to zimbra 5.0.5.

That I must modify to solve it?

Nobody else has reported this, as far as I know. So it sounds like something with your setup.

Does this occur on every HTML message? Can you open a new bug in bugzilla and attach a "SHow Original" of one of the HTML messages.

that same mail I see well with thunderbird or other client.

So it sounds like something with your setup.
where I can review setup?, in preferences I already did it, and not works to me.
