我去看了man sendmail 有下面的发现:
-fName
Sets the name of the from person ( the envelope sender of the mail). This address
may also be used in the From: header if that header is missing during initial
submission. The envelope sender address is used as the recipient for delivery
status notifications and may also appear in a Return-path: header. This flag
should only be used by trusted users (normally root, daemon, and uucp) or if the
person you are trying to become is the same as the person you are. Otherwise, an
X-Authentication-Warning header is added to the message.
你是说-f的标志吗? |
