解决方法
1创建文件${CFDIR} /mailer/copymail.m4：
PUSHDIVERT(-1) ifdef(`COPYMAIL_MAILBox',`define(`COPYMAIL_MAILBox',`postmaster')')dnl POPDIVERT ######################################### ### COPYMAIL Mailer specification ### ######################################### VERSIONID(`$Id: cpsendmail.html,v 1.2 2002/06/14 18:39:10 freeman Exp $')dnl LOCAL_CONFIG D{COPYMAIL}COPYMAIL C{CP}${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添加到结束sendmail.mc
define(`COPYMAIL_MAILBox',`user@domen') MAILER(copymail)
3编译并安装新的sendmail.mc
4重新启动sendmail
5测试
