Unable to receive email proofs sent through a midsourcing instance

This article addresses an issue where email proofs in Adobe Campaign Classic fail to reach intended recipients due to a Midsourcing 2 server problem.

Description description

Environment

Adobe Campaign Classic

Issue/Symptoms

Each time an email proof passes through the Midsourcing 2 server, it is not being received on the intended email addresses. This seems to be happening only in the case of proofs.

When you have an on-premise environment setup with 2 containers, and both containers are running on the mta process, proofs and deliveries won’t be sent if  mta from container 2 is being used.

Note:  The issue does not occur on using the mta from container 1.

Resolution resolution

Start a stat server on container 2 as well. This will allow the mta of container 2 to connect to it and send proofs and deliveries.

Cause

A slow connection between the mta server of container 2 and the stat server of container 1 caused this issue.
