  #在M
  ##### @(#)procmail.m4 8.11 (Berkeley) 5/19/1998 #####
  Mprocmail, P=/usr/bin/procmail, F=DFMSPhnu9, S=11/31, R=21/31, T=DNS/RFC822/X-Unix,
  A=procmail -f- -Y -m $h $f $u
  # (空此行一定要先空tab)


  # 在my name for error messages设定的后面加上下面两行
  # Avoid host map lookups if address has this pseudo-domain on it CPprocmail


  # 在Ruleset 98后面加上下面设定
  # Filter all mail through procmail
  #
  # Strip the pseudo-domain and continue (already gone through the filter)
  R$*<@$+.procmail>$* $@ $1<@$2.>$3
  R$*<@$+.procmail.>$* $@ $1<@$2.>$3
  #
  # No pseudo-domain, send to filtering mailer
  R$*<@$+.>$* $#procmail $@/etc/procmail/filter.rc $:$1<@$2.procmail>$3
  R$*<@$+>$* $#procmail $@/etc/procmail/filter.rc $:$1<@$2.procmail>$3

  9、建立过滤档filter.rc

  vi /etc/procmail/filter.rc
  范例文件内容如下:
  LOGFILE=/var/log/procmail.log
  NL=”
  ”
  LOGABSTRACT=no


  POISONED_EXECUTABLES=/etc/procmail/poisoned-files
  INCLUDERC=/etc/procmail/html-trap.procmail


  :0 # re-send the message
  ! -oi -f “$@”
