Yes. MAIL FROM: <> makes it so that the receiving mailer doesn't bother
trying to bounce the message. It is part of RFC821.
... Of course, server-SMTPs should not send notification
messages about problems with notification messages. One way to
prevent loops in error reporting is to specify a null reverse-path
in the MAIL command of a notification message. When such a
message is relayed it is permissible to leave the reverse-path
null. A MAIL command with a null reverse-path appears as follows:
MAIL FROM:<>
