maildrop 一些例子

发件人是指定的邮箱地址:
if ((/^(From|Sender|Return-Path):.*[e-mail]/))
{
  to “$HOME$DEFAULT/.Trash/.”
}

自动回复:
cc “| mailbot -A ‘X-Sender: $FROM’ -A ‘From: $FROM’ -m ‘$HOME$DEFAULT/autoreply.cf’ $SENDMAIL -t -f ””

主题过滤:
if ((/^Subject:.*testddd/))
{
  to “| $SENDMAIL -f ” ‘”$SENDER”‘ ” [e-mail]”
}

包含**过滤:
if ((/iqssss/:b) || (!/wuzhr/:b) || (/^Content-Type: *multipart/mixed/))
{
  echo “notall”
  EXITCODE=77
  exit
}

收件人是批定的邮箱:
if ((/^To:.*[e-mail]/))
{
  to “$HOME$DEFAULT/.Trash/.”
}

白名单:
foreach /^(Return-path|From): .*/
{
  if (lookup( getaddr($MATCH), “$HOME$DEFAULT/whitelist.cf” ))
  {
    to “$HOME$DEFAULT/.”
  }
}

黑名单:
foreach /^(Return-path|From): .*/
{
  if (lookup( getaddr($MATCH), “$HOME$DEFAULT/blacklist.cf” ))
  {
    EXITCODE=0
    exit
  }
}

邮件转发:
to “| $SENDMAIL -f ” ‘”$SENDER”‘ ” ”

postfix拒绝mailfrom和from不一致

                if ( /^From: *!.*/ )
                {
                    getaddr($MATCH2) =~ /^.*/
                    from = $MATCH
                    mailfrom = $SENDER
                    log "from: $from"
                    log "mail from: $mailfrom"
                    if ( "$from" ne "$mailfrom" )
                    {
                        exit
                    }
                }
