Email users of password expiration

I've run into many situations where we've needed to email end users of their pending password expiration. Sometimes it's remote users who don't see the password change alerts, sometimes it's just a way to show that the end user was notified their password was expiring. Here's the script I've cobbled together from various sources. It emails their password once it's 7 days out. I usually schedule the script to run daily at noon.

 # Please Configure the following variables....
$smtpServer="smtp.domain.com"
$expireindays = 7
$from = "noreply@domain.com"
$logging = "Enabled" # Set to Disabled to Disable Logging
$logFile = "c:\logs\pwdemaillog.csv" # ie. c:\logs\pwdemaillog.csv
#$testing = "Enabled" # Set to Disabled to Email Users
$testRecipient = "adminuser@domain.com"
$date = Get-Date -format ddMMyyyy

    if (($logFilePath) -ne "True")
    {
        # Create CSV File and Headers
        New-Item $logfile -ItemType File
        Add-Content $logfile "Date,Name,EmailAddress,DaystoExpire,ExpiresOn"
    }
} # End Logging Check

Import-Module ActiveDirectory
$users = get-aduser -filter * -properties Name, PasswordNeverExpires, PasswordExpired, PasswordLastSet, EmailAddress |where {$_.Enabled -eq "True"} | where { $_.PasswordNeverExpires -eq $false } | where { $_.passwordexpired -eq $false }
$DefaultmaxPasswordAge = (Get-ADDefaultDomainPasswordPolicy).MaxPasswordAge
# Process Each User for Password Expiry
foreach ($user in $users)
{
    $Name = $user.Name
    $emailaddress = $user.emailaddress
    $passwordSetDate = $user.PasswordLastSet
    $PasswordPol = (Get-AduserResultantPasswordPolicy $user)
    # Check for Fine Grained Password

    }
    else
    {
        # No FGP set to Domain Default
        $maxPasswordAge = $DefaultmaxPasswordAge
    }

    $expireson = $passwordsetdate + $maxPasswordAge
    $today = (get-date)
    $daystoexpire = (New-TimeSpan -Start $today -End $Expireson).Days
     
    # Set Greeting based on Number of Days to Expiry.
    # Check Number of Days to Expiry
    $messageDays = $daystoexpire
    if (($messageDays) -ge "1")
    {
        $messageDays = "in " + "$daystoexpire" + " days."
