Duplicate email (postfix and thunderbird)

Postfix:

• sender_bcc之類規則引發重複信件: http://phorum.study-area.org/index.php/topic,36329.html
• 使用no_address_mappings: http://www.freespamfilter.org/forum/viewtopic.php?f=10&t=332&sid=3d2e544a70b72505222814d2659a859a, 不過需要virtual domain好像就不能用這個方法?

Server端處理有一點麻煩, 用Thunderbird解法?
