Apple’s Mail.app refuses to display HTML mail for my .Mac account for mail sent by Apple.
I received the .Mac newsletter tonight and also a notice about the mini store opening in my area and both were broken disjointed text versions. You’d think they could nail the text version, but if the HTML does not work through an entirely Mac pipe, I guess not.
HTML mail sent to my main account viewed in Mail.app is a mixed bag. Some work, some don’t. Thunderbird works fine for HTML on all the messages I’ve gotten in all my accounts.
