I have a client running Exchange 2007. The message size limit for mailboxes was set at 10MB (I believe this is the default setting). One of the users was expecting a message with an 11MB attachment and didn't receive it. They are using a DoubleCheck SPAM appliance that shows the message hitting the server this morning - my question is: how long does the message sit on the server? Is it held in a queue or is it immediately bounced because it exceeds the size limit? Should the sender receive a NDR?
Any feedback would be much appreciated.
