A cmdlet-like email script

I'm currently working on a database monitoring, datacollection and automation project using PowerShell. In this project I often find m self in need of sending a status or warning email when some event occurs - For a while I've just used code much like what I posted here on my blog back in december 2006, but last night I spend a bit of time writing up a cmdlet like "Send-SMTPmail" function once and for all.
Please feel free to comment the script, its functionality and implementation.

Script to extract disk space usage through WMI

This script can be used to extract information regarding sapce usage (actually free disk space in percent) from one or more servers or cluster. Since the script uses Win32_Volume, it can also recognize mountpoints.

$outData = @("")
$server = $args[0]
$dataFromServer = Get-WmiObject Win32_Volume -ComputerName $server | Select-Object SystemName,Label,Name,DriveLetter,DriveType,Capacity,Freespace

foreach ($currline in $dataFromServer) {
    if ((-not $currline.name.StartsWith("\\")) -and ($currline.Drivetype -ne 5)) {
        [float]$tempfloat = ($currline.Freespace / 1000000) / ($currline.Capacity / 1000000)
        $temppercent = [math]::round(($tempfloat * 100),2)
        add-member -InputObject $currline -MemberType NoteProperty -name FreePercent -value "$temppercent %"
        $outData = $outData + $currline
    }
}

$outData | Select-Object SystemName,Label,Name,Capacity,FreePercent | sort-object -property FreePercent | format-table -autosize
