I am brand new to exchange server 2010 and want to set up some transport rules. (using .plc.uk ) domain extension as an example. (I also put this on superuser forum a week ago but no help so far)

• E-Mail will with keyword “PROTECT:” in subject message must be sent to .plc.uk E-Mail Addresses. CC,BCC sent to .plc.uk E-Mail Addresses.

• E-Mail from .plc.uk will only be allowed to be received by certain personnel, I have a list Tom Dick and Harry no one else other than these are allowed.

• Remote devices will not be allowed to download attachments for mail with keyword “PROTECT:” in subject E-Mails. They will be using Outlook Web App(OWA) or Outlook Anywhere

Are all three rules possible? or would I need to use message classification?

Could someone please help with Powershell cmdlet

New-TransportRule -Name "PROTECT_TO_PLC" –  ?????

New-TransportRule -Name "PLC_TO_AUTHLIST" –  ?????

New-TransportRule -Name "PROTECT_NOT_TO_RD" –  ?????

Hub Transport rules don't affect OMA <-> Client Access, so #3 is out. The others should be possible, but you may have to use classifications. There's no way to say if message is NOT for {people}, at least not directly. You can set policies for OMA devices, including encryption requirements; that may solve #3 for you (it doesn't keep select e-mails off the device, but can keep the devices secure) –  Chris S Feb 27 '12 at 14:58
So to clarify you would suggest a white list (group) for people that can receive a .plc.uk message. –  icecurtain Feb 27 '12 at 15:20
If you read your first one closely, it doesn't make sense. –  Bret Fisher Feb 28 '12 at 2:24

1st One (didn't test):

New-TransportRule -Name "FW_PROTECT" -SubjectContainsWords "PROTECT:" -CopyTo "cc@plk.uk" -BlindCopyTo "bcc@plk.uk" -Enabled $true

2nd One (didn't test):

New-TransportRule -Name "PLC_TO_AUTHLIST" -FromAddressContainsWords "plc.uk" -RejectMessageReasonText "You can't send this message." -RejectMessageEnhancedStatusCode: "5.7.1" -ExceptIfSentToMemberOf: "GroupOfAllowedUsers@domain.com" -Enabled $true

The ExceptIfSentToMemberOf is a distribution list of people that are allowed to receive the email.

3rd One is not possible IMO.

E-Mail will with keyword “PROTECT:” in subject message must be sent only to .plc.uk E-Mail Addresses. Even if the the addresses are in the CC,BCC addresses fields. So the to email address must end in .plc.uk nothing else. –  icecurtain Mar 2 '12 at 9:54
So these messages originate from the same plc.uk Exchange server, and you want these messages to reject to any non-plc.uk address? –  Bret Fisher Mar 2 '12 at 15:24
The exchange server is not plc.uk, but if a user send a message from the within the exchange server with the word PROTECT: in the subject message then it must send it to a PLC.Uk address. –  icecurtain Mar 2 '12 at 15:48
OK, I added the first rule. Let me know if this doesn't fully answer your question. –  Bret Fisher Mar 4 '12 at 23:29
