Error message with a script sending emails to multiple recipients.

Question

Hi all,
I am very new with powershell scripting and I want to request your attention and help on this issue.
I am getting this error message "Send-MailMessage: An invalid character was found in the mail header: ','" given by this script:
Param (
[string]$Path = "C:\Temp\",
[string]$SMTPServer = "smtp.domain1.com",
[string]$From = "[email protected]",
[string[]]$To = "[email protected],[email protected]",
[string]$Subject = "New backup file"
$SMTPMessage = @{
To = $To
From = $From
Subject = "$Subject at $Path"
Smtpserver = $SMTPServer
$File = Get-ChildItem $Path | Where { $_.LastWriteTime -ge [datetime]::Now.AddHours(-6) }
If ($File)
{ $SMTPBody = "`nThe following files have recently been added/changed:`n`n"
$File | ForEach { $SMTPBody += "$($_.FullName)`n" }
Send-MailMessage @SMTPMessage -Body $SMTPBody
I found the ForEach() approach but when I put it inside I get an infinite loop.
Many thanks for any suggestions

[string[]]$To = "[email protected],[email protected]",
should be
[string[]]$To = @("[email protected]","[email protected]")
