Excellent Post. Very helpful.
Thank you.

It is a “low effort” approach. I’ve permitted entire IP ranges in some cases before, usually for things like desktop apps that need direct SMTP relay but the pc’s are on a DHCP range without reservations (reservations might sound like a logical solution to that, but they add “yet another thing” to manage and will of course break if the user gets a new pc or logs on to a different one).

I wouldn’t do it on insecure networks, eg wireless where a guy in his car outside the building uses your server to relay spam.

And as long as they aren’t creating an open relay that can be exploited from the internet then it’s probably fine.

Hey, Paul –

We just built an Exchange 2010 and migrated all the mailboxes from the old 2003 Exchange box. My integrator says he usually adds ALL the IP addresses (and in our case, all the subnet ranges) into the Relay Connector. This is opposed to just devices that usually send mail — scanners, copiers, accounting/equitrac servers.

What say you about adding all my IP ranges into the Exchange 2010 Relay Connector?
Thanks.

Hey Paul,

My list of receive connectors is truncated … Even when results outputted to .txt file. Is there a way to have it show the entire list

[PS] C:\>Get-ReceiveConnector “internal relay” |fl remoteipranges >C:\Users\uwhadmin\Documents\output\remoteip.txt

RemoteIPRanges : {10.150.12.21, 10.150.31.63, 10.150.21.35, 10.0.10.13, 10.30.15.27, 10.0.1.7, 10.150.11.14, 10.150.50.191, 10.150.53.196, 10.150.53.197, 10.150.50.195, 10.150.52.197, 10.150.50.192, 10.150.50.193, 10.150.11.62, 10.0.1.24…}

Hi Rodney, I guess a bit of script logic to check for existing IP’s first would do the trick. I’ll see if I can come up with something.

I notice that if you have an error like “The value ‘xx.xx.xx.xxx’ is already present in the collection.”", the script stops.
Anyone knows how can I make the script still running and putting the rest of the IPs to the receive connector even with some errors ?
Tks in advance.

Thanks, I managed.
None of the IP addresses were already present. The trick for me to get it to work was to specify
In the first line the full connector name (including the server name) instead of only the connector name.

Thanks!

The answer is in the error message. Two of the IP addresses you’re trying to add are “already present in the collection”.

Strangest thing
Exchange 2010 SP1+Rollup 4. When running the import with a text file containing a list of IP addresses
the following error occurs for each IP address:

[PS] C:\Windows\system32>Get-Content .\iplist.txt | foreach {$RecvConn.RemoteIPRanges += “$_”}
Exception setting “RemoteIPRanges”: “Cannot convert value “System.Object[]” to type “Microsoft.Exchange.Data.MultiValue
dProperty`1[Microsoft.Exchange.Data.IPRange]“. Error: “The value ’1.1.1.1′ is already present in the collection.”"
At line:1 char:47
+ Get-Content .\iplist.txt | foreach {$RecvConn. <<<< RemoteIPRanges += "$_"}
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : PropertyAssignmentException

Exception setting "RemoteIPRanges": "Cannot convert value "System.Object[]" to type "Microsoft.Exchange.Data.MultiValue
dProperty`1[Microsoft.Exchange.Data.IPRange]". Error: "The value '10.4.10.210' is already present in the collection.""
At line:1 char:47
+ Get-Content .\iplist.txt | foreach {$RecvConn. <<<< RemoteIPRanges += "$_"}
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException

Can someone assist ???
