Protocol event sink sounds good, but I don't have the skillset to develop it, nor does anyone on my staff at the current time. Perhaps in the future I Can go to that, but I'm in a pinch to get something in place within the next day or so.
Since I don't really know what I'm looking for, I had a hard time finding resources with the variables related to the sub routine used for an smtp event sink. Do you have any links I could check out for that information, and one for an SMTP protocol event sink? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chris Scharff Sent: Tuesday, November 22, 2005 9:19 PM To: Exchange Discussions Subject: RE: SMTP Event Sink help If $sender is always external this could be completed with an SMTP protocol event sink. That allows you to return a custom response (i.e. 550 you do not have permission to send to this recipient) without having to take delivery of the mail. If the users in question are members of a DL you'll either need to do an additional LDAP query to make sure they are not members of the DL. If they are members of a DL and you do need this validation, but don't want to make the query yourself[0] you would need to use a post categorizer event sink as it's not until that point that the full list of recipients is available.[1] A protocol event sink would be the cleanest way to implement this[2], but probably not the easiest. Not sure that helps but hopefully it gives you some ideas. [0] Or if $sender is not always external. [1] Well, technically that's not true it's available at the categorizer level, but in general I think post-cat event sinks are probably easier to write than cat event sinks. [2] Always prefer to stop a message before it's transferred if possible.

Here's what I'm trying to accomplish: If e-mail is sent TO [EMAIL PROTECTED] OR [EMAIL PROTECTED] and it's NOT from [EMAIL PROTECTED] then dump the mail. Ideally, dump the mail means reject it and send the user an undeliverable response of some kind. But in reality, it could be as simple as send the mail to badmail. I came up with this script, but am looking for some validation on if I'm using the correct msg variables and if it's the proper way to do this. This dumps to badmail, because I really don't know how to do anything else. I hacked up a sample script off MS's site as it is <SCRIPT LANGUAGE="VBScript"> Sub IEventIsCacheable_IsCacheable() 'To implement the interface, and return S_OK implicitly End Sub Sub ISMTPOnArrival_OnArrival(ByVal Msg, EventStatus) Dim envFlds Set envFlds = Msg.EnvelopeFields 'Check to see if the e-mail send to the mailbox has efax.com in the senders domain If ((Msg.To = "[EMAIL PROTECTED]") or (Msg.To = "[EMAIL PROTECTED]")) and InStr(1, Msg.From, "sender.com") = 0 Then 'Do not deliver, place message in the Badmail directory. envFlds ("http://schemas.microsoft.com/cdo/smtpenvelope/messagestatus";) = 3 envFlds.Update 'Commit the changes of the message status 'Skip remain event sinks EventStatus = 1 End If End Sub </SCRIPT> _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
