Google continues to supply me with cute little bugs, but this time I have a really serious one for you. In fact, this one has been driving me crazy for the last year.
Gmail has a spam filtering system that works according to some secret, as usual, logic. Yet this logic is faulty: it defines as spam e-mail coming from respectful domains. Recent victims: International Institute of Software Testing and the University of Illinois. Both do not spam. One wonders how stupid a spam filtering mechanism should be to classify uis.edu as a spamming domain...
But all that’s only the first half of the problem. After an angry correspondent calls you to demand an answer for an e-mail you've never seen, and you wish to tell Gmail that xxx.com is a trusted domain - bang! You cannot. You can only categorize a specific e-mail address as safe. Tomorrow somebody else from the same organization mails you - you guessed correctly, it will go to spam. Contacting Gmail support? Try it, and you will see it's as real as Atlantis.
