[Xymon] first alert generated twice

[Camelia Anghel]

Hello all,
I'm having this issue where the first alert is sent twice since I added html_mail.pl script.
The alert message is generated  with mail -s  and html_mail.pl script, after that the emails are generated only by the html_mail.pl script.

When I run this command:

bin/bbcmd hobbitd_alert --test myserver msg

00017758 2013-03-13 12:13:06 *** Match with 'HOST=myserver' ***
00017758 2013-03-13 12:13:06 Mail alert with command 'mail -s "Hobbit [12345] myserver:msgs CRITICAL (RED)" canghel at mymail'
00017758 2013-03-13 12:13:06 Matching host:service:page 'myserver:msgs:servers' against rule line 69
00017758 2013-03-13 12:13:06 *** Match with 'SCRIPT /xymon/server/ext/html_mail.pl canghel at mymail FORMAT=PLAIN SERVICE=msgs COLOR=red REPEAT=10m RECOVERED' ***
00017758 2013-03-13 12:13:06 Script alert with command '/xymon/server/ext/html_mail.pl' and recipient canghel at mymail
00017758 2013-03-13 12:13:06 Matching host:service:page myserver:msgs:servers' against rule line 71

The entries in the hobbit-alert.cfg look like this
Host=myserver
  SCRIPT /xymon/server/ext/html_mail.pl canghel at mymail FORMAT=PLAIN SERVICE=msgs COLOR=red REPEAT=30m RECOVERED

How do I disable the mail -s?

Thank you,
Camelia Anghel
