Hi,

We are having problems with one of our customers they cannot receive emails from one of their suppliers. I have looked in the log and have found the email hitting our server. See below.

Code: Select all

Trace: Tracing message with Message ID [B9898FB34FF04E25BE26C6F0797E3A89.MAI] from the SMTP Inbound Queue

Result: [B9898FB34FF04E25BE26C6F0797E3A89.MAI] was not routed from the SMTP inbound message queue by the local MTA Service. This most likely means that the message was not completely recieved by the connector.
Important: Message ID [B9898FB34FF04E25BE26C6F0797E3A89.MAI] does not seem to have been routed through MailEnable queues (an error most likely occured when receiving this message).

Any ideas?

It is very difficult to determine why the connection is dropped via inspecting the receiving mail server's logs (typically the sender will have the actual reason for dropping the connection).

At a guess though, it is possible that there may be a mal-configured router obscuring the transmission of large data packets between your server and the sender. The solution is to have the owner of the router correct the MTU setting or you may consider lower the MTU setting on your server.
