ITPEC FE Morning October 2019 Question 36
ITPEC FE Morning October 2019 — Question 36 of 80
Bcc header removal in SMTP — identify which e-mail header is stripped during transfer.
Bcc (Blind Carbon Copy) is removed from the message headers by the sender's mail server before SMTP transmission, so recipients cannot see who received a blind copy.
Why not others:
- (b) Date — remains in headers; shows when the message was sent
- (c) Received — added by each relay server along the path; never removed
- (d) X-Mailer — optional header identifying the mail client; stays in headers
Key rule: "Blind" means invisible to recipients — the SMTP server strips Bcc addresses from headers after using them for envelope routing.
