Question
Response: 421 SMTP incoming data timeout - closing connection
We have an issue sending mail from Exchange 2003 to an EXIM mail server. All we can ascertain from sniffing the traffic is that we get Response: 421 SMTP incoming data timeout - closing connection. Prior to that we see [TCP Window Update] smtp > 46320 [ACK] seq=275 ack=18494 win=58820 len=0
Is it possible that we need to adjust our MTU size on our router?
