The following problem seemed to start only a few weeks ago. Our Exchange 2K3 server is not delivering/receiving email with attachments over around 4MB. The server fails to send (they just sit there in the queue blocking any other traffic going to our smarthost) and it also fails to receive emails too. The MX records of our host address is pointed directly at our Public IP address so incoming emails do not go via the smarthost.
I've checked the policy settings and I've got a 100MB limit on my mailbox. I've checked the SMTP Virtual Server settings and can find nothing wrong.
Any Ideas?
