[Bro] Question about no mail from bro-2.5.4

[wangdj at ffcs.cn]

Hi, 

I write a bro shell file to test function of notice mail. But when i run this shell, the mailbox "dj5521 at 163.com" does not receive any mail.
The following is the shell file:

@load base/protocols/conn
@load base/protocols/http
@load base/frameworks/logging
@load base/frameworks/notice

module HTTP;

export {
redef enum Notice::Type += {
Http_Notice_Plicy
};
#redef Notice::mail_dest = "dj5521 at 163.com";
}

redef Notice::mail_dest = "dj5521 at 163.com";

event http_message_done(c: connection, is_orig: bool, stat: http_message_stat)
{
local message = fmt("====http done====");
NOTICE([$note=Http_Notice_Plicy, $msg=message,
$conn=c,
$identifier=cat(c$id$resp_h,c$id$resp_p,c$http$uid)]);
}

hook Notice::policy(n: Notice::Info)
  {
  print "===========>run HTTP policy<=============";
  if ( n$note == HTTP::Http_Notice_Plicy )
      add n$actions[Notice::ACTION_EMAIL];
  }

When i run this file, i do not get any error and bro produces notice.log and weird.log correctly.  I have installed mail tool on my centos system already. 
Could you please help me to look what wrong with this shell file?
