Exchange message not delivered
Trying to send an email to a client, with a PDF attachment. I can send a regular email fine, but the PDF attached is not. This used to work. I am curious, is this being blocked from my end or the clients? I think clients because it says postini and I am running Exchange 2007.

Sounds to me like the destination postini server is rejecting the message due to the content (file attachment)...

hello
that's what i assumed. but on my message headers i dont see any communication between the exchange server of mine and the clients mail, like i normally do when i get other errors or what not.

That's because your mail is being rejected by the PostIni server before your message is even attempted to be delivered to his e-mail server (that's how PostIni works). So the message headers should reflect communication between your server and the PostIni server.

Right, I dont see communication between myself and postini though, i see it listing my exchange server but no other remote service.

Sorry, I mis-spoke - since PostIni isn't accepting the message they won't have modified the message at all (including headers). So, the message headers would likely indicate the message has been handled only by your server, but the non-delivery report will indicate rejection by PostIni.
