I have an exchange 2007 mailbox server with another hub server behind that. I have increased the send connectors to 15mb however the most mail I can get out is 7.2 meg. I get a message from exchange from the hub server
The recipient's e-mail system is currently full or overloaded and can't accept any messages. Microsoft Exchange will not try to redeliver this message for you. Please try resending this message later, or provide the following diagnostic text to your system administrator.
The first odd thing is why do I get this message if its a size limit as this indicates an issue with the recipient's server which is misleading.
Secondly even allowing for 33% mime encoding I am still only getting roughly half the specificed size out.
Any ideas on both these issues thanks : )
