We increased our max message size to 15 MB from 10 MB. I updated the Global setting in the Organization section of the MMC.
I then changed the default Receive connectors to the increased size limit and successfully sent email of this increased size.
We had one Receive connector for all of our HubTransport servers used for those select internal Servers that could relay SMTP email to outside recipients. I forgot to update the Max message size on this Receiver Connector to the increased valule.
I then updated this value and restarted the transport service on the server,
I still cannot send an increased size email through this server; the email is rejected for being too large.
can anyone think of what I am missing to get these new increased message size limis to work for this particular Receive Connector?
I am running Exchange 2008 on Windows 2008 servers.
