The Mail app on my 4S is deleting new email on one of my Yahoo accounts before I can read them. I'll open the account and see several new emails, and the app starts deleting them immediately. The emails aren't moved to the trash, bulk, or anywhere else. All of my past emails are unaffected. I can view the new emails on Yahoo's website, however. All of my other Yahoo and Gmail accounts work normally on my iPhone. I've tried deleting and adding the account back to the iPhone, but the behavior remains.
Any help would be appreciated.
