Sorry for top posting...

What command are you using for the notification? / How are you sending
these mails?

We originally used a simple one like this...
which just 'echos' text in to the mail command
=============================================
# 'notify-by-email' command definition
define command{
        command_name    customer-notify-by-email
        command_line    /bin/echo "To: $CONTACTEMAIL$\n\
Subject: $SERVICESTATE$ alert for $HOSTNAME$/$SERVICEDESC$\n\
\n\
\n\
 application=\"Nagios\"\n\
 node=\"$HOSTNAME$\"\n\
 type=\"$NOTIFICATIONTYPE$\"\n\
 service=\"$SERVICEDESC$\"\n\
 criticality=\"$_SERVICECRITICALITY$\"\n\
 service status=\"$SERVICESTATE$\" (for $SERVICEDURATION$)  last time
it was \"$LASTSERVICESTATE$\"\n\
 message=\"$SHORTDATETIME$ - $SERVICEDESC$ on $HOSTNAME$
$SERVICESTATE$ - $SERVICEOUTPUT$ - $TOTALSERVICESCRITICAL$ services
critical in total\"\n\
 msg=\"$LONGSERVICEOUTPUT$\"\n\
 checked using=\"$SERVICECHECKCOMMAND$\"\n\
" | /usr/bin/mail $CONTACTEMAIL$
}
=============================================



Then went for a neater solution that work work across our different platforms
this sends the arguments from nagios in to a wrapper scrip for mail...
=============================================
# 'notify-service-by-email' command definition
define command{
        command_name    notify-service-by-email
        command_line    /etc/nagios/global/commands/nagios-mailx.sh -t
$CONTACTEMAIL$ -s "$SERVICESTATE$ Service Alert:
$HOSTNAME$/$SERVICEDESC$" -y "$NOTIFICATIONTYPE$" -m "***** Nagios
*****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService:
$SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState:
$SERVICESTATE$\nCriticality: $_SERVICECRITICALITY$\n\nDate/Time:
$LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n\nSee:
$_SERVICENAGIOS_URL$host=$HOSTNAME$&service=$SERVICEDESC$\n\nCommand:
$SERVICECHECKCOMMAND$"
