B、Never open any e-mail attachment.
C、It’s always safe to open an e-mail attachment from a friend.
D、Whenever you receive an e-mail, you should make a call to make sure whom it comes from.

解析从第四自然段最后一句 If an e-mail with attachment (附件) comes from an unknown sender，or unexpectedly from a known sender，it should not be opened．可知，不可以盲目地打开邮件的附件。所以正确的答案为A。
