monit 4.7-beta2: email alerts issue

[Rishikesh Dongre]

Hi,

I have downloaded, installed new beta version 4.7 on my machine.

My monit.conf file is like 
---<---
set alert address@hidden

check device root path /dev/md/dsk/d0
   if space usage > 90% then exec "/usr/local/monit-4.7/msg"
   alert address@hidden with mail-format { subject: Monit Alerts -- $EVENT / > 
90% on $HOST }
--->---

On matching resource limit, email alerts receiving at both addresses 
(address@hidden and address@hidden) which is not in previous versions.

Is it a bug?

Please help.

Thanks,
rishi
