451 Error on Client Disconnect

[StojanovicVladimir]

Hey,I'm encountering a consistent 451 error when a client disconnects while I'm receiving emails using Haraka. Despite the error, the emails are still being received successfully. Below is the relevant output from swaks:

-> This is a test mailing
->
->
-> .
<** 451 (74CB270A-0C85-4073-BC4E-8E8F5C58E27E.1)
-> QUIT
<- 221 srv524042 closing connection. Have a jolly good day.
=== Connection closed with remote host.

My server is not under load, and I would like assistance in resolving this issue. Thank you!

There is insufficient information here for anyone to help you. You need to include the Haraka version, configured plugins, the full swaks output, and probably also the Haraka logs.
