Message Size Attachment Rejection when sending outbound.

Requested #550 5.3.4 SMTPSEND.OverAdvertisedSize; message size exceeds fixed maximum size ##

I have checked and adjusted all the connectors and transport server settings to 40MB:

[PS] C:\Windows\system32>Get-TransportConfig | fl *Max*

MaxDumpsterSizePerDatabase      : 25 MB (26,214,400 bytes)

There are no special SmartHosts that the internet send connector sends to. I created a new send connector and disabled all of the other send connectors and tried to send the message again with the same error. I also checked the corresponding ADSI Attributes to see if they did  not apply or were wrong for some reason:

I went to ADSI Edit and browsed to Configuration\Services\Microsoft Exchange\GASFP\Global Settings
I then looked at the following of Message Delivery Properties:

delivContLength: This is the incoming message size limit that corresponds to theMaxReceiveSize parameter in the Set-TransportConfigcmdlet.
submissionContLength: This is the receiving message size limit that corresponds to theMaxSendSize parameter in the Set-TransportConfigcmdlet.
msExchRecipLimit: This is the maximum number of message recipients that corresponds to the MaxRecipientEnvelopeLimit parameter in the Set-TransportConfig cmdlet.

The first two were set to 40MB and the last was set to 5000 recipients. All these settings are correct.

I am stuck at this point and any help would be appreciated.

Thanks,
