Also remember, you should always set the max message size limit at the
connectors and global level slightly higher than the actual limits
advertised to the end users. If you advertise 10MB as the max message
size, then you may have to set a max message size limit of 11 or 12MB at
the connector levels and Global levels. This is required to cover the
additional headers that are added to the user's original message which
increases the total message size.

" Message size limits in Exchange 2003
Did you know that there are four separate places where you can set
message size limits in Exchange? If any one of them has a lower size
limit than another, then that restriction applies. So you can set
size limits at the following levels:
* Globally
* At the connector. You can configure different message sizes for
each connector.
* at the SMTP Virtual server
* and at the individal user level
There's a good example in the KB article which explains how it works
and helps to troubleshoot issues and stops you going round and round
in circles. But be aware of the conditions that can prevent message
delivery:
In this example, the following size limits have been configured:
* The global setting is set to 5 MB.
* The Exchange SMTP connector is set to 3 MB.
* The SMTP virtual server is set to 4 MB.
* The user mailbox setting is set to 2 MB.
Because of these settings, users in the Exchange 2000 or Exchange 2003
organization can send and receive messages that are a maximum of 5 MB.
Users can send messages through the connector that are a maximum of 3
MB. All mail that passes through the SMTP Virtual Server (sending or
receiving) is limited to 4MB. The individual user, whose mailbox
setting is 2 MB, is also limited to sending and receiving messages
that are a maximum of 2 MB."
