bcc cc ?

CC = Carbon Copy
BCC = Blind Carbon Copy

Cc 即係所有放響"cc"欄o既收件者都可以收到個e-mail message, 而且cc header o既收件者會全部列晒出o黎響header度睇到. 如果你Reply All, 所有Cc header o既收件者都收到個reply.

Bcc 同cc相似, 但係收件者就唔響e-mail header度出現, 所以收到封e-mail都未必知道封e-mail send過俾一o的"神秘人". 如果你Reply All, 所有Bcc header o既收件者係唔會收到個reply.

如果你唔想o的e-mail收件者互相知道有咩其他人收到, 好多時會用Bcc.

e.g. send封e-mail俾你一大堆朋友, 而佢o地又唔係互相認識, 咁你可以選擇Bcc, 因為可以避免朋友e-mail address外洩

Bcc 的全寫是 blind carbon copy
Cc 的全寫是carbon copy

The Shortcomings of Cc:using the Cc: field, both the original recipient and all the recipients of the carbon copies see the To: and Cc: fields including all the addresses in them. This means that every recipient gets to know the email addresses of all the persons that received your message.

bcc : BLIND CARBON COPY 隱藏副本
