Configure Smtp Virtual Server in windows Server using Powershell-(Relay,Connection)

Question

Using powershell I have to enable SMTP and

• Add relay Ip
• Add connection IPs
• Set Access Control Authentication

I found following code for the above operation

$GetSMTP = Get-CimInstance -Namespace "root\MicrosoftIISv2" -Class "IISSMTPServerSetting" -Filter "Name ='SmtpSvc/1'"
$RelayIps =  @(10,92,32,83,127,0,0,1)
$GetSMTP.RelayIpList = $RelayIps
Set-CimInstance -InputObject $GetSMTP

$GetSMTP
$GetSMTP = Get-CimInstance -Namespace "root\MicrosoftIISv2" -Class "IIsIPSecuritySetting" -Filter "Name ='SmtpSvc/1'"

$NewConnectionIps = @(
                     "10.92.32.80, 10.92.32.81";
                     "10.92.32.83,127.0.0.1";
                      )
$GetSMTP.ipgrant += $NewConnectionIps
Set-CimInstance -InputObject $GetSMTP

$GetSMTP

The above powershell code executed successfully and it list as it is added.

But when i connect to smtp server, the following error is throwing

I have a found a solution to solve the above issue, To delete the folders inside "C:\inetpub\mailroot" and where i am able to start the default Smtp Virtual Server, but again facing an issue while click smtp vitrual server properties

Adding Relay , connection IPs and Authentication Basic for SMTP

$Networkip =@()
$Networks = Get-WmiObject Win32_NetworkAdapterConfiguration -ComputerName    localhost | ? {$_.IPEnabled}
foreach($Network in $Networks)  {  $Networkip = $Network.IpAddress[0]  }

Adding Relay and Authentication Basic for SMTP

$ipblock= @(24,0,0,128,
32,0,0,128,
60,0,0,128,
68,0,0,128,
1,0,0,0,

0,0,0,0,
0,0,0,0,
0,0,0,0,
0,0,0,0,
255,255,255,255)

$ipList = @()
$octet = @()
$connectionips=$arg[0]       
$ipList = "127.0.0.1"
$octet += $ipList.Split(".")
$octet += $Networkip.Split(".")

$ipblock[36] +=2 
$ipblock[44] +=2;
$smtpserversetting = get-wmiobject -namespace root\MicrosoftIISv2 -computername localhost -Query "Select * from IIsSmtpServerSetting"
$ipblock += $octet
$smtpserversetting.AuthBasic=1
$smtpserversetting.RelayIpList = $ipblock
$smtpserversetting.put()

Adding Connection for SMTP

}

$iisObject = new-object System.DirectoryServices.DirectoryEntry("IIS://localhost/SmtpSvc/1")
$ipSec = $iisObject.Properties["IPSecurity"].Value

# We need to pass values as one element object arrays
[Object[]] $grantByDefault = @()
$grantByDefault += , $false            # <<< We're setting it to false

$ipSec.GetType().InvokeMember("GrantByDefault", $bindingFlags, $null, $ipSec, $grantByDefault);

$iisObject.Properties["IPSecurity"].Value = $ipSec
$iisObject.CommitChanges()

$bindingFlags = [Reflection.BindingFlags] "Public, Instance, GetProperty"

# to set an iplist we need to get it first
if($isGrantByDefault)
{
    $ipList = $ipSec.GetType().InvokeMember("IPDeny", $bindingFlags, $null, $ipSec, $null);
}
else
{
    $ipList = $ipSec.GetType().InvokeMember("IPGrant", $bindingFlags, $null, $ipSec, $null);
}

# Add a single computer to the list:
$ipList = $ipList + $connectionipbuild

# This is important, we need to pass an object array of one element containing our ipList array
[Object[]] $ipArray = @()
$ipArray += , $ipList

# Now update
$bindingFlags = [Reflection.BindingFlags] "Public, Instance, SetProperty"
if($isGrantByDefault)
