Import Export IP list on Allowed Relay Receive Connector

If you are migrating from Exchange 2003 to 2010, when you export the list of allowed relay devices, following this article http://support.microsoft.com/kb/935635 the output will typically be in this format:

10.1.0.1
10.1.0.2
10.1.0.3
10.1.0.6
10.1.0.7
10.1.0.8

Name the file IPList.txt
So, with the script below, you can import the list of ip addresses on your receive connector

$RecvConn = Get-ReceiveConnector "Ex2010\AllowedRelay"
Get-Content .\IPList.txt | foreach {$RecvConn.RemoteIPRanges += "$_"}
Set-ReceiveConnector "Relay Connector" -RemoteIPRanges $RecvConn.RemoteIPRanges

When you are migrating from Exchange 2007 to 2010, we use powershell command to export the list, and a powershell script to import

Here is the powershell command to export the list. Change the exchange 2007\allowedrelay part to be the correct server\receive connector name.

(Get-ReceiveConnector "exchange2007\allowedrelay").RemoteIPRanges | select Lowerbound,Upperbound,RangeFormat | sort-object Lowerbound| export-csv c:\rc.txt –NoTypeInformation

Use this script to import it onto the exchange 2010, change the second line to be the correct exchange 2010 server name \ receive connector name

$csv = "c:\rc.txt"
$rc = "EX2010\RelayConnector"
$impcsv = import-csv $csv
foreach($line in $impcsv)
{
$ipAdd = $line.LowerBound
$conn = Get-ReceiveConnector $rc
$conn.RemoteIPRanges += $ipAdd
Set-ReceiveConnector $rc -RemoteIPRanges $Conn.RemoteIPRanges
}
