Puppet users - Feb 2010 - Puppetmaster doesn't want to send mails

Hi,
I configured my "puppet.conf" with:

/[puppetmasterd]
         environments    = testing,production
         templatedir     = /var/lib/puppet/templates

         reports         = tagmail,rrdgraph,store
         reportdir       = /var/lib/puppet/reports
         reportfrom      = root@hostname
         rrddir          = /var/lib/puppet/rrd
         rrdinterval     = $runinterval
         rrdgraph        = true/

and "tagmail.conf" with:

/all: email1@my.domain/

I use : /puppetmasterd --no-daemonize --verbose --debug/ to look at debug:

/...
info: Processing reports tagmail, rrdgraph, store for xxx.my.domain.com
info: No messages to report to myemail/
...

I don''t understand why puppetmaster thinks that it has nothing to
send...
Am I missing something?

Thanks in advance!
