Spam mails

某些外國人實在很怪, 防Spam防到某種令人討厭的地步了.

這是國外客服信偶而會收到的一種自動回覆信:

I apologize for this automatic reply to your email.

To control spam, I now allow incoming messages only from senders I have approved beforehand.

If you would like to be added to my list of approved senders, please fill out the short request form (see link below). Once I approve you, I will receive your original message in my inbox. You do not need to resend your message. I apologize for this one-time inconvenience.

簡單地說, 因為A先生不想收垃圾信, 所以想寄信給A先生的人, 必須點那個連結去請A先生將你的e-mail列入"可以寄信給A先生"的名單.

問題是, 這樣一個要我點選的連結, 我又怎麼知道你不是想收集我e-mail的垃圾郵件呢?
