Yahoo is the worse 'free email account' source of spam. Friends in Sweden say they can't send outgoing mail despite having had the same Yahoo accounts for more than 15 years. The problem is no response from the Yahoo servers at different times of the day. We block all incoming emails from mail servers with host names resembling home Internet connections and also when the HELO/EHLO doesn't resolve to the host name. Consequently we don't get spam. -- Paul. England, EU. Our systems are exclusively Linux. No Micro$oft Windoze here.
