I have used tethereal to capture the communication between the server. This is what I have between the 354 go ahead and the 451 error: 45.636243 10.1.0.10 -> 10.1.0.143 SMTP Response: 354 go ahead 45.636415 10.1.0.143 -> 10.1.0.10 TCP 1847 > smtp [FIN, ACK] Seq=227 Ack=479 Win=65057 Len=0 45.639529 10.1.0.10 -> 10.1.0.143 SMTP Response: 451 Incomplete DATA I am afraid it doesn't mean anything to me. Should I try capturing the full packet information rather than trying just the summary of the packets. I have included the all the communication between the windows computer with nova backup on it and the linux server running qpsmtpd.
