WARNING: Yahoo hides spam from third-party email apps
Yahoo Email filters out their idea of spam into a Yahoo spam folder and never makes it visible to third-party email apps such as Mac Mail or Thunderbird. I found this out the hard way when several critical emails did not arrive as expected, only to find them later in Yahoo's spam folder via their webmail interface. There is no way I've found to turn this off. You can supposedly train their spam filter by marking individual emails as "not spam", but this means you still have to login constantly to Yahoo and check the spam folder for legitimate email.
