Description:
Issue
A delay in traffic acknowledgment from the server side might cause emails with attachments to stall through an SMTP-proxy with Gateway AntiVirus enabled. This in turn causes the email to be deferred on the sender's end.When this occurs, you see this SMTP-proxy log message: ".. smtp response '451 4.7.0 Timeout waiting for client input.."
