1 创建文件 ${CFDIR}/mailer/copymail.m4：

PUSHDIVERT(-1)

ifdef(`COPYMAIL_MAILBOX',,
    `define(`COPYMAIL_MAILBOX', `postmaster')')dnl
POPDIVERT

LOCAL_CONFIG
D{COPYMAIL}COPYMAIL
C{CP}${COPYMAIL}

LOCAL_RULE_0
# Send all mail to copymail mailer
R$* < @ $+ . $~{CP} . >     $#copymail $@ $2 . $3 . ${COPYMAIL} $: $1 @ $2 . $3 . ${COPYMAIL}
# if mail has been processed by copymail mailer, process it usual way...
R$* < @ $* . ${COPYMAIL} >  $1 < @ $2 . >

# Send message to original recipient + additional mailbox: COPYMAIL_MAILBOX
Mcopymail, P=/usr/sbin/sendmail, F=fmSDFMu, S=0, R=0,
    A=sendmail -N never COPYMAIL_MAILBOX.${COPYMAIL} $u

2 添加到末尾 sendmail.mc

define(`COPYMAIL_MAILBOX',`user@domen')
MAILER(copymail)
