Since the error occurs within less than 1 second of the start of the

dropped for some reason. It is probably best to use a packet sniffer
(ethereal works well in my experience) to check what the client and
server actually send.
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.
Well, yes, ... but I think you have shown enough to say that the client
has asked to close the connection without sending any data.
What do the client logs say? Do you have a support arrangement with the
vendor of the client software?
