If you're not aware of the Yahoo Mail Problem, I've detailed it and my attempts at fixing it here: The Last Psychiatrist: Most Frustrating Technology of 2010 (so far): Google Android 2.1 update was supposed to fix the problem, and it did, but there's a new one. For some reason, mail sent from the android via Yahoo mail delivers fine, but in the "Sent" folder of Yahoo Mail it marks the email as having an attachment. It doesn't have this attachment in the recipient's email box; only in the sender's sent mail box. The problem is that if you send the email to a .gov address- or to anyone with tighter spam filters, the email gets marked as spam because of the fake attachment that isn't there. I've tested this on a .gov, .mil, and an insurance company's email. This is certainly trivial in comparison to 45000 copies, but... Also, has anyone noticed that upon update, it copies multiple emails out of your deleted folder and re-inboxes them?
